Hi Grant,
As part of the internal bug report process, I have also tested this issue on the latest version of the main branch, and it appears that the crash no longer occurs there. I could not find a changelist meant to solve this specific issue, but there has been a lot of development going into state trees for some months now, so I guess some other development or bug fix ended up resolving this as well. Some CLs that might have done it are 39175013 and 39253656 from january, but I’m not entirely sure. Let’s hope the fix can make its way to UE 5.6..!
Best regards,
Vitor
