Please tell me this is in the US

Sounds like the good old fucked bootloader after system update

A good place to start because it's a likely culprit is anything mentioning "OOM" (which refers to Out Of Memory)

There are many reasons one could choose to hate Snap packages, and this not one of them. It's like hating a webbrowser because it spawns 20 processes that (the horror) you would all see when you run ps. It's just a part of how container technologies work.

Purist, hard-line stuff like this will honestly just get you nowhere in 2023. I get where you're coming from, but it's simply not realistic. This is what browser extensions are for.

You should, and you will :) X11 is legacy, and is going to die. The only question is whether you're going to try and hold on to a broken system riddled with security vulnerabilities for as long as possible until you're forced to switch, or whether you're just going to enable what is mostly already the default stack on most desktop Linux systems anyway.
