I have already tried to run as an administrator but unfortunately it didn't work.
Close the EpicGames Launcher completely
Local data carrier (C. → Programs → Epic Games → Fortnite → FortniteGame → Binaries → Win64 →
FortniteClient-Win64-Shipping
, FortniteClient-Win64 Shipping_BE,
FortniteClient-Win64-Shipping_EAC
and right click Fortnite Launcher → Compatibility → Run program as administrator → Apply - Ok
3. Restart
If someone knows what else you can do, they don't want to reinstall it.
You could click on the 3 dots in the Epic Launcher in the Library tab, then on Fortnite, and then click Check.
Then the game will be checked for incorrect and missing files.
Thanks, I had already tried it, but it didn't work, but I simply reinstalled Fortnite 3 times until it worked
