UE5 crash

Hi, after play execution and when returning to edit mode, a crash occurs unexpectedly.

the project ran without any problems in UE4. Since the change to UE5 in connection with World Partition, I have this problem.

does anyone have any idea what could cause this.

thank you in advance

I have this EXACT same issue. Were you able to find any resolution to it?

no, not yet. We will have to wait and hope that the bug will be fixed.
