Warning CreateExport: Failed to load Outer for resource ... for many blueprints

this worked perfectly for me in ue5.2. thanks

Unfortunately, none of the suggested solutions worked for me.

The issue was caused by my Game Instance file, which is under development. Interestingly, it was not listed as part of the Warning CreateExport logs (they were all about my PCG subgraph…)

In my case, my resolution steps were:

  1. Move the GI file from the content folder (while the unreal editor is closed) with Windows Explorer.
  2. Start Unreal
  3. While the editor running, move the GI file back with Windows Explorer to the original location (my last changes were not yet committed to git…)
  4. Duplicate the GI file Unreal and delete the original one.

Problem solved. I initially thought the file was corrupted, but it was working fine (even the original was opening and compiling ok after step 3. I also unselected it from maps & modes, but no luck.

The indicator for me was that in my Rider console logs, I found a statement about versions of the GI file that were different than the expected one just before all warnings related to the CreateExport entries…

Hi all!

As DomRV said…Unfortunately, none of the suggested solutions worked for me.

So here’s how I Fexed it on 5.5.1.

1 - Change the Level Name to whatever you want…
2 - Create a NEW BP Class Actor ( in my case was an BP_ActorClass what was creating the problem )
3 - Save the file
4 - Close the Project
5 - Reopen it
6 - Delete the BP_actor you created.
7 - Right click button on Content folder
8 - Update Redirector References
9 - Save the project and close it
10 - Reopen it again

That was the solution for me.

Thank you all

Thank you, it solved my problem using Unreal 5.4.4 version!
