we just run into a problem of one of my team mates machine. On that machine we get the warning “Warning CreateExport: Failed to load Outer for resource …” a lot (<800) in many blueprints. And after that the editor is crashing most times. I copied his project folder over to my machine and there is everything running fine. We reinstalled the launcher and unreal as well as completely deleted and force synced the whole project from P4. But nothing is helping. On all other team machines in our team the project is running fine.
After deleting and resynching the whole project I get once the error:
“Failed to import ‘C:/Program Files (x86)/Epic Games/4.12/FeaturePacks/StarterContent.upack’. Failed to create asset ‘/Game/StarterContent’”
But unreal is installed with starter content.
One artist is completely blocked atm. please help.
I am getting to happen in 4.18.1 a lot for some reason. Not sure what is causing the data corruption but it is nasty. The editor won’t load and the Blueprint class breaks. I thought it might be caused by having 4.17 and 4.18 open at the same time with the same asset being used by two different projects.
I am getting the exact same error with 4.19.2. I purchased a new laptop so that I could work on the project while I am traveling, as well as show off what we have completed so far to potential investors and publishers. Today, I downloaded all of the new files from our Perforce server to my laptop after checking everything in on my desktop and I started getting this same error on the laptop.
SO i just ran into this problem in the past week or so, we are using git hub and doing all of our source control through it.
We are also using git LFS.
I played around with a couple of different things to get past this error, including the help ideas suggested above. I can’t give a concrete step by step solution to the problem. But I can give the things i did to ultimately get past this problem.
Delete the %userprofile%\AppData\Local\UnrealEngine (as suggested by )
Delete the internal files like Timdhoffmann suggested (I deleted only the Saved and Intermediate folders)
At this point i repulled my repo, and things started to work.
I believe that this essentially purges all the references within your git delta history (i could be wrong if anyone can correct). SO THE WARNING HERE is if you don’t want to lose all of those references within your git history don’t do this.
This effects the references in all of the repo’s branches.
The rabbit hole I went down to solve this problem:
Happened to me with 4.23.1 rather frequently when you delete referenced content, this even for a few files can take extensively long, making me quit the editor through the windows task manager. Deleting the cache folders as outlined above fixed it for the most parts, some errors remain though …
I recently got the same issue.
The problem for me was that the level I was loading had previously contained a blueprint that been force deleted.
As I know the only one way to solve it is recreate a dummy blueprint with same name of unloaded blueprints.
Could use reference viewer (right click on content folder) to locate the missing blue print.
Hello! I am having this same issue. I have done all of the suggestions including trying to migrate my files. I still have no solution. Unreal is telling me that it can’t reach a file i deleted and although i deleted and it can’t find it, it is still applying its affects. Has anyone found an alternative solution?
