Tried 2.3.2 dev some weeks ago to test it with Bambu H2D. Deinstalled after it crashed constantly without error message. Had occasional crash of v2.3.1 since then with this error message, Now 2.3.1 and 2.3.2 dev crashes every time.
Problem exists on two machines with very different hardware (desktop/laptop).

What did I try:

install latest Nvidia driver
deinstall and reinstall v2.3.1 and 2.3.2 dev
