random crashes after lightdb truns off the screen

My intsall is stable after I log in but if I don't it randomly crashes and reboots without any logs after lightdm turned off the screen.
Nothing in journalctl or any other logs. I do not have a serial port or something like that and since the screen is off I can't see if the kernel prints something like a panic.

Any idea how to track down what's happening?

randomly crashes and reboots without any logs after lightdm turned off the screen

Spontaneous reboots are because
* underpowered
* overheated
* bad RAM
* broken CPU

https://wiki.archlinux.org/title/Ryzen#Random_reboots is very common (if you have such CPU)
Otherwise please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

(just for a general oversight of the configration)
