Manjaro froze and then rebooted

Hello!

i hope that someone can help me with the following issue:

Yesterday out of the blue, while I was watching a video on YouTube, my desktop froze completely (the sound stopped working, the keyboard and the mouse became unresponsive as well), and then, after a few seconds, the machine rebooted.

Please find below the output of two commands:

journalctl --boot -0 --priority=err

I would recommend a BIOS update. B460M GAMING HD (rev. 1.0) Support | Motherboard - GIGABYTE Global

This can create sometimes unwanted outcome … mostly unpredictable, even tho some systems can run with both, but you should chose just one.
For PulseAudio install manjaro-pulse package,
For PipeWire install manjaro-pipewire package.

The actual issue i see is this

Since is an AUR package, did you build it again after each update ?

Thank you for your suggestions. When it comes to BIOS, I would rather stick with the current firmware, at least for the time being (as they say, if it ain’t broke, don’t fix it).

With regard to audio, I did a quick search online and it looks like I use PulseAudio only (manjaro-pulse installed).

Here is the output of pactl info command:

And here is the output of pactree -r pipewire command:

As far as bluemail is concerned, then I did not build it after each update. Since it crashed at the splash screen, I added --no-sandbox to the application’s arguments in the desktop environment. And I run it sandboxed (firejail bluemail --no-sandbox %U).
