Its been like 2-3 weeks that I didn’t get this. All I have been doing all day was painting the landscape and sculpting it a bit (smoothing parts). Then when I wanted to do a save-all, this problem happened.
Why?
I tried doing a few Build All Levels and clicking do not save. Then I tried Save All and it worked. Sounds like corruption that got fixed by the build all level.
Hi Browserice,
First thing to check is if you have another copy of your project open in another UE editor - that can cause this error.
Another thing is check how much HDD space you have left…
I only have one UE editor and always work with one project at the time. I only have one project.
There is like 3TB disk space left.
Hello @Browserice
Were you able to get the issue resolved with the project failing to save? If not, it may be worth checking Task Manager to ensure that there isn’t a second copy of Unreal Engine open. (As the user prior mentioned, this is generally the culprit with this error) If that doesn’t resolve it, I’ll be happy to check into additional steps to help you resolve this. I hope this helps!
The only workaround I have found is to do 3-4 times a build and when it asks to save (usually the ones he could not save), I just reply continue (so no saving). Then I try a save all and it works.
It also happens if by chance you have cleared your system Cache
