Crash on Behavior tree and when getting pawn on BP

Development Programming & Scripting
1

Hi everyone !

I have a problem with UE. I have a Blueprint that have to get pawn, cast him and get information from him.
But when I have to open it, UE crash. only solution I found is to move in windows explorer pawn asset then open my blueprint that use it and finaly move pawn asset to right place. After this I have to recreate all references in blueprint.
This solution waste my time because each time I open my project, this bug reappear.

And I have another probleme, when I run a behavior tree to an AI controller, UE crash at launch in viewport. behavior tree do nothing for now so is weird.

Thanks in advance for helping me.

Hi ,

Does this occur on a clean project with no additional content? Additionally, which version of editor are you currently using?

I was able to reproduce this crash on my end and have entered in a crash report, TTP#348051 to be assessed by development staff. I am certain that problem lies within pawn blueprint, though I am not sure what is causing this crash specifically. Thank you!
