Random PC reboots since VoH. Anyone else with same behavoiur?

Since the new addon, my pc randomly restarts when playing d4. This is only happening, when playing voh. Has anyone else encountered this behaviour? Already checked several things (ram, drivers, cpu, gpu,...) but no success. Event viewer says "failed to create dump file". On some occasion, i get a game crash without reboot, and a blizzard error (sry, dont have a screenshot, since i'm on my mobile atm) just wondering, if someone accounteted similar issues. Can give specs layer if needed, but atm just wondering, if there are more people with this behaviour. I did already disable all the overlays (discord, nvidia,...)
