Unreal Engine Launcher - Corrupt data found

The launcher won’t open and just comes up with Corrupt data found every time I try. Anyone know how to fix this?

I haven’t figured it out yet myself. But having it done to me twice now I know what triggers it is when you have unreal installed on an external drive and delete the derived data cache folder to clear up space. For some reason after that, it tries to look for all its app data off of the C: drive. So even if you go to uninstall unreal, you probably can’t because it’s gonna ask you to browse for you msi since it doesn’t know where it is. Let me know if you discover a solution
