Gentlemen, help me, I decided to download UE 4.27, created an empty project, moved the chair a little, decided to save it, but I constantly get this error. I checked if there are 2 editors in the dispatcher - no. Restarting the PC did not help. Deleted UE, downloaded epic games again, created a project, same story. How to fix it ?
That really does look like the ‘two copies of the editor open’ problem. But if it’s not that, then how about doing a ‘save as…’?
Nothing, I just can’t figure out what it is.
If you’ve crashed recently and restarted there can occasionally be an Unreal thread still running and not the whole editor.
ok, then what should I do? I have already reinstalled the editor 3 times
what if you change the derived data cache for your project? or delete all your temp files
i gave access to the files of the editor folder and it helped me
I think it could be a background program is reading the files. Try find a supicious program on Task Manager.
