I have done some work on my project in UE5 now but suddently it started placing random folders from earlier versions of the game or even other games in my content browser. This happens on startup and mostly if I took a one or two days break. It is also not possible to remove some folders with simply deleting them in UE5 or even the windows explorer. I am sick of a dozend folders stacking up in my content browser. Please help? Thank you alot.
