Hello. I really need help. When downloading plugins from fab from the library, an infinite initialization occurs. I can’t solve this problem for several days. Please help. I tried reinstalling the launcher, but it didn’t help.

I agree, clearing cache is a good first step. If the issue remains active after that, I would suggest a full uninstall/reinstall of all Epic software:

  • First, uninstall the engine, launcher, asset packs, etc
  • Next, open the registry directory HKEY_CURRENT_USER\Software\Epic Games\Unreal Engine\Builds, and delete any build entries
  • Finally, delete the folders %userprofile%\AppData\Local\UnrealEngine and %userprofile%\AppData\Local\UnrealHeaderTool
  • After that, no elements related to UE should be left in your system
  • Now, reinstall UE launcher from scratch, and only add the latest version of the engine
  • After the process is complete, test adding elements from FAB again
