"Unable to Check Out From Source Control!" message when attempting asset restore after crash

I recently crashed and had a few assets backed up through autosave. When attempting to reload the editor, I got a message to restore those autosaved assets. After continuing, I get the message:

"Unable to Check Out From Source Control!

The following assets could not be successfully checked out from source control:
/Game/Blueprints/Skills/Active_Skill
/Game/Blueprints/Units/TB_Skeleton"
and then the editor loads with those assets not restored. I am not using any form of source control, and have been able to restore autosaved assets prior to version 4.7.3

If you go into your \Unreal Projects\PROJECTNAME\saved\backup\ file you should be able to retrieve a backup copy of your assets. If you copy/cut these out of the backup folder and paste them directly in place of the copy in your contents folder, it should recover the file.

Hi ,

We have not heard from you in several days. I am marking this thread as answered for tracking purposes. If you are still experiencing this error, please comment with the requested information.

Thanks for providing the workaround, but that doesn’t actually fix this recurring issue. Please let me know if there’s any info I can provide to actually resolve the issue.

In your editor, do you have source control enabled or disabled? You can check this on the main toolbar next to the save icon.

it is currently disabled

I haven’t been able to reproduce this on my end thus far. Do you have any specific steps that I can take to reproduce this on my end? Did you update the project from another engine version after the crash and then the errors started occurring or did you crash while using 4.7.3?

I experience this following crashes as well. Currently using 4.7.6. Not sure when exactly this began happening, but probably at some point while using 4.7.x.

Source control is disabled.

Hi ,

Do you have any steps I can take to reproduce this error on my end?

I get this on crashes too, esp with the memory leak issues. I have no source control but it tells me a file can’t be checked out when I try to restore it. 4.10.4 pc

Hi ,

  • Does this occur in a clean, blank project with no additional content or is it limited to one project?
  • What steps did you take to reproduce this error on your end?
  • Can you post your crash logs and callstack so I can take a look?

If you go into your \Unreal Projects\PROJECTNAME\saved\backup\ file you should be able to retrieve a backup copy of your assets. Seems to work for me! UE 4.17 MacOS with Perforce enabled

I use git but without connecting to editor and I get this error every time it crashes (in multiple projects).
4.21

Still getting this error in 4.27 …

Still a problem in 5.3, though I’ve experience this since 4.x

It happens every single crash that leads to the crash report dialog, without fail.
