If you are still experiencing this issue please try the following:

  • Save all changes you’ve made to the project,
  • Close UEFN & ensure it is fully closed/background processes complete until “Launch” becomes visible in the Epic Games Launcher rather than “Running”,
  • Navigate to the project folder in which you are receiving the error in your Windows file browser,
  • Move ONLY the .urc folder to your desktop (don’t delete it for now just in case it is needed) so that it is no longer in the project folder,
  • relaunch UEFN,
  • open the project,
  • a new .urc folder will be created and your state should be reset, hopefully unblocking you to check in again,
  • once you confirm all is working again you can delete the folder you moved to the desktop

We have a fix to prevent this issue from happening coming in an upcoming release but this workaround should unblock you in the meantime

I just tried this for my UEFN project. But now my project has bad frames. 8 frames per second. I’m thinking its cause its trying to reset the .urc file and its taking a toll on UEFN? Do I just keep waiting until its done or should I try to migrate the files onto a new project.

@TediKoi sorry to hear you’re experiencing this, does the FPS recover after you Check-in Changes?

trying it now and UEFN seems like its frozen. Maybe it’s trying to check in the changes, but not sure.

@TediKoi Did you end up able to check in? If not please message me in discord at epic_garren and I can try to help you get unblocked
