Hi Brenden,
So far I have been unable to reproduce this crash. Would it be possible for you to provide a minimal repro project, or a list of repro steps to follow starting with a blank project?
By the way, here are two approaches you can try to use to rename the assets:
Approach 1 - Rename normally, then run the fixupredirects commandlet
After renaming the MPC asset, quit the Editor and run the following command line (docs):
"<UNREAL_PATH>\Engine\Binaries\Win64\UnrealEditor-Cmd.exe" "<PROJECT_PATH>.uproject" -run=ResavePackages -fixupredirects -autocheckout -projectonly -unattended
Approach 2 - Prevent the creation of a redirector
Before renaming the MPC asset:
- Temporarily disable revision control
- Make sure it is not referenced by any level assets or collections
This will hopefully allow you to perform the rename without creating a redirector.
Please let me know if one of these solutions works for you.
Best regards,
Vitor
