Crash after update to 4.11 at map open

Hi,

we went back to working with 4.10 for the last weeks to meet some deadlines, but are back on the 4.11 upgrade now. Unfortunately I can’t send the whole project as it is a commercial game.

I did delete the Saved and Intermediate folders, but the issue still remains. I’m not sure how to reproduce it with a blank project either, do you have any ideas what I could try next?
