TrueNas gives you a lot of options and it isn't too obtuse. I recommend Scale over Core. Avoid it if you only have the one drive as the os won't share its drive with the rest of the system. Also, while you can use it with only one "storage" drive, it will complain because it uses ZFS and expects you to set up redundency across at least two drives. Might be a hassle for your form factor, but worth a look.

Unless the info is out of date (which is likely) kern.log syslog or messeges.
Have you checked the logs in /var/logs?
Watch a truenas setup for it snd compare the permissions maybe? I got it working on my truenas server but it takes a long time to spin up so it seemed borked but was just slow to start. Not directly comparable, I know, but any port in a storm.
Use the comments on protondb. They often list tweeks and troubleshooting steps that have been taken. Check steam community posts for specific games. You can also make your own post if nobody else has had your issue. General searches will usually get you where you need to go. I use kagi but generally anything not google works.
The only thing that I've encountered that may be relevant, the flatpack version of steam on popOS had issues and after installing from apt my games started working as expected. So possibly reinstall steam with apt vs the popshop.
If there is a pin set, decimal on the numpad, else Ctrl or ESC.
It's easy to recover... if you're on site.
A used Google Pixel or Samsung Galaxy should be pretty cheap. Just make sure they support whichever version of Android you want to develop on. Pixel 6's are under $200 USD on eBay currently and should all be upgradable Android 14.
Krita is pretty good.
If you're looking for a wide range of games tested, NizVicious. FreddysGamingBenchmark focuses on the steam deck. EtaPrime usually test all his builds in linux at some point but it's mostly the same games as he's a hardware channel (newer titles get added though).
