Project names may not contain a space

Hello, I tried to continue work on project without internet connection, but when I launched UE throw UE4Editor.exe (Epic Games launcher said that my profile dont saved for offline, so dont forget to enable offline mode in settings), I cant open my project with this error


But starting project from Epic Games launcher didnt have this problem, and Unreal Tournament and Battle Breakers have spaces. Is it a random bug of this version?

Ok, looks like UE4Editor.exe dont like if you rename project and folder name to get spaces.
