5-0EA GPU VRAM error: Using auto possess on spawn with default AIController for Character will crash engine?

Hi there!

I have an NVidia 3080 with 16gb/16gb dedicated/shared memory. Enough to get things going. Everything runs smooth and no problem at all, until I set my Character to “auto possess on spawn” with the default AIController. The Character has a C++ base class which produces signals to control it with “Add Movement Input”. Not possessing the Character will not move it at all.

Weirdest thing: The VRAM usage goes up linear until it crashes AFTER I close the simulation or exit the game…

Trying to debug this for hours now, really frustrated and out of ideas. Any help or hint is appreciated.
