Not trying to be obtuse, just my train of thought went in another direction.

Plugins

os-apcupsd
os-cpu-microcode-intel
os-nextcloud-backup
os-squid
os-tayga
os-theme-vicuna
os-wol

I too have this issue reboot/shutdown issue, and it began after a couple updates ago where others seemed to agree it was a Crowdsec problem as Patrick suggested, but I don't have that plugin installed.  I thought I was an outlier and was just going to do a fresh install one of these days.  But out of the list of plugins you listed, I also have these two installed:

-os-cpu-microcode-intel
-os-nextcloud-backup

So perhaps for us others without Crowdsec, we can concentrate on those two plugins as a possible cause?  Neither is crucial for me to have installed and can test later tonight if removing one (or both) of those fixes my reboot issue, and perhaps if you have time you can try as well?  Might be a simple fix after all...  :)

It used to work about a year ago just fine.  However, if I remember correctly Cloudflare said it was being abused and made a change that prevents using a regular WireGuard configuration or client. I and others had been using it with great success, then one day it just stopped working. As far as I know, the only way to connect is to use their official Warp program/app on each device.
