Crash during movie play

this crash (during the movie play), is my first time since I use vero.
maybe is only bad luck…

the crash during the stand by (the original issue of this thread) it happens after 1 week (more or less) of stand by.

But, the strange behavior is that before the hard reboot (unplug power cord) with the command journalctl --list-boots --no-pager i could see all the reboot since when the logs are activated. After the hard reboot, only one!
