Fortnite Crashing or Not Launching on PC
Identify the exact failure, repair local files and Launcher state, then escalate through drivers and Easy Anti-Cheat before committing to a full reinstall.
Check Epic service status and the exact error first; then verify Fortnite files, clear Launcher cache, update the GPU driver and repair Easy Anti-Cheat.
In Epic Games Launcher, open Library → Fortnite → three dots → Manage → Verify. If that fails, completely exit the Launcher and clear only its named webcache folders. For crashes after an update, Epic recommends updating or reinstalling the graphics driver. Reinstall Fortnite only after lower-cost checks fail.
“Fortnite does not work” is not one technical problem.
The fastest fix depends on where the launch stops. Record the exact message and timing before changing files, drivers or security settings. Epic explicitly recommends searching an error message first because a code-specific solution may exist.
The Launcher may return to Launch, show Running without a visible window or display a service-specific error.
Fortnite may close during startup, lobby loading, mode selection or gameplay. Note the exact stage and whether it follows an update.
Corrupted data, out-of-memory and anti-cheat messages have narrower fixes than a generic crash checklist.
Rule out an outage and an unsupported PC before rebuilding files.
A widespread service issue cannot be repaired from one Windows installation. A PC below Fortnite's minimum requirement also needs a compatibility decision, not an endless reinstall loop. Keep these checks brief so this page stays separate from the full system-requirements article.
If Fortnite login, game services or the Launcher show an incident, monitor the official status before modifying a healthy local installation.
Use Epic support for the displayed code or sentence. A targeted “Corrupted data” or anti-cheat fix outranks generic advice.
Check that the PC meets Epic's current minimum requirements. Save the detailed component comparison for the dedicated specifications guide.
Exit the Launcher and restart Windows. This clears a stuck process and provides a cleaner test before file repair.
Verify before reinstalling: Epic can replace damaged local files in place.
Verification checks the Fortnite files on the PC and repairs files that differ or are corrupted. Epic states that the process does not affect saved data.
Let the Launcher finish signing in, then open Library.
Select the three-dot menu on the Fortnite entry and choose Manage.
Click Verify and wait until validation completes. Large installations can take time.
Do not change several other settings during validation. Test Fortnite after the process finishes.
If the same error returns, keep the exact wording and proceed to the next relevant layer.
Running Verify repeatedly without a changed result is not a diagnosis. Move to cache, driver or anti-cheat checks.
Clear only Epic's named webcache folders after fully exiting the Launcher.
A stale Launcher cache can cause display failures or prevent the Launcher and games from working correctly. This is a Launcher repair, not a Fortnite save-data reset.
Use the system-tray Epic Games icon and choose Exit. Confirm the Launcher is no longer open.
Press Windows + R, enter %localappdata% and select OK.
Go to EpicGamesLauncher → Saved. Do not delete unrelated folders.
Delete webcache, webcache_4147 or webcache_4430 only if they appear, matching Epic's current instructions.
Open Epic Games Launcher again and allow the interface cache to rebuild.
If the same failure remains, move on rather than repeatedly deleting the regenerated cache.
A crash after an update and a silent anti-cheat failure need different repairs.
Epic identifies graphics drivers as a common post-update crash layer and Easy Anti-Cheat as a specific dependency when Fortnite shows Running but never creates a visible game window.
Use NVIDIA, AMD or Intel's official path for the installed GPU. Epic says updating or reinstalling the graphics driver can mitigate hitching or crashes after an update.
When Fortnite is Running without opening, follow Epic's EAC Windows Service repair instructions before reinstalling the entire game.
Epic's escalation list includes disabling background applications. Test with a clean, minimal set rather than uninstalling random software.
Epic includes an administrator launch as a later permission check. Do not leave unrelated programs elevated or weaken system security.
“Running” with no Fortnite window points to a narrower Epic checklist.
Epic's dedicated support page prioritizes file verification, Easy Anti-Cheat repair and a Windows Security check. Apply the security step carefully: exclusions reduce scanning for the selected path.
Repair different or damaged files with Library → Fortnite → Manage → Verify.
Use Epic's Easy Anti-Cheat Windows Service article. Do not download a replacement service from an unofficial site.
Epic documents adding the Fortnite folder to the exclusion list when security blocking is the suspected cause.
Never exclude an entire drive. Use only the Fortnite folder and reassess the exception if it does not solve the launch failure.
Reinstall in a controlled order and stop when the same evidence repeats.
Epic's full PC checklist goes beyond the common repairs, but the order matters. Reinstalling a large game before testing small local layers costs time and can reproduce the same driver, drive or background-software problem.
Use Epic's documented Launcher reinstall procedure if its interface or services remain broken after cache repair.
Use a full game reinstall only after verification, cache, driver and EAC checks fail. Preserve any records of the original error.
Epic includes a different-drive reinstall for repeated corrupted-data cases, which can help separate installation from storage issues.
Disable conflicting background software methodically and use Windows or manufacturer diagnostics for suspected drive errors.
Epic has a post-update crash procedure that deletes GameUserSettings. This resets local settings, so use the exact support article rather than deleting the whole FortniteGame folder blindly.
If every software layer passes and the same hardware-linked failure remains, Epic's checklist ends with the hardware manufacturer.
Fortnite PC crashing and launch questions
Why is Fortnite crashing or not launching on my PC?
Possible causes include a service incident, exact error condition, damaged files, stale Launcher cache, driver problems, Easy Anti-Cheat, background conflicts or an unsupported PC. Identify the symptom before reinstalling.
How do I verify Fortnite game files?
Open Epic Games Launcher, choose Library, open Fortnite's three-dot menu, select Manage and then Verify. Wait for validation to finish. Epic says saved data is not affected.
What do I do when Fortnite says Running but does not open?
Epic recommends verifying files, repairing Easy Anti-Cheat and then checking whether Windows Security is blocking the Fortnite folder. Treat any exclusion as a narrow security exception.
How do I clear Epic Games Launcher cache?
Exit the Launcher, open %localappdata%, then EpicGamesLauncher and Saved. Delete only Epic's named webcache folders if present and relaunch.
Should I reinstall Fortnite when it keeps crashing?
Reinstallation is a later step. First check the exact error, minimum support, files, cache, graphics driver and Easy Anti-Cheat. Reinstall only after those lower-cost checks fail.
