System crashes

Hi All


I have a 2018 mac mini. Randomly it seems to crash but not whilst being used. I can sleep the mac in the evening and come back in the morning and sometimes it's crashed and rebooted. Sometimes I will then log it in again ut not open any application and sleep it again and come back to find it's crashed again.


I have re-installed Monterey and also wiped all setting creating a new user from scratch but still suffer the same issue. I did try removing my usb hub incase this was the issue, but no joy. The only other thing connected to it is the apple cinema display, connected via and apple adapter the thunderbolt port.


Crash report attached thanks

Disable Sleep, it’s unnecessary on later Macs, all pain, no gain. To disable, check “Prevent…” in Energy Preferences and uncheck everything else, should fix. You can leave the display off time as is, unrelated to Sleep. Shut for long absences i.e. > 2 hours.
