Crash on opening map only in shipping build

I got a main menu map and a map for the actual game. When starting the game, it first goes into a entry map, this then opens the menu map. And from there, depending on what menu entry is selected, it opens the game map. So far so good. But when exiting the game, i open the menu map again and here is the crash.

It is only happening in shipping build. PIE, development and debug build are fine and never crash. Shipping build crashes every time.

Any idea whats going on here?
I have activated logging on the shipping build and it seems to crash on some code for particle systems.
Can’t attach the file as it just doesn’t start the upload. If anyone wants to have a look i can upload it somewhere. However here is the last part of it:
