Crash on open 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 GPU particle systems on garbage collection. I have attached the log.

Also tried to use -NoVerifyGC on development and debug builds to try and reproduce the issue with a debuggable build. But still, no crash on development and debug.
