Xbox Series X Barely Functions

For about a month now my Series X has been randomly hard crashing to a green screen. I pretty much only play Destiny 2 or Wonderlands at the moment. Sometimes it will crash on the dashboard or while streaming [insert service here].

I've tried to look up the issue and it seems pretty widespread with little to no actual help on the problem. Here are all the "troubleshoots" I've attempted:

- reset my console and kept games and apps (twice)
- factory reset it (once)
- tried running non-optimized versions on an external (wouldn't let me play them anyway)
- held down all of the buttons
- reset the blue ray drive (even though the games are digital)
- deleted local saved data
- turned off Auto HDR
- gotten a new HDMI cable
- unplugged it for a while
- reset my MAC address
- had an external fan on it at all times it is running (it's not over heating from what I can tell and the fan does work)
- removed the back panel, removed the fan, and cleaned whatever minimal dust was in there (it's in a well ventilated spot)
- probably some other things.

The only thing I can do is plug it into a wall because my house is old and numerous outlets in a room are rarer than you might think.

Long story short, nothing works; the more I attempt to try and troubleshoot the problem, the more it wants to crash. I'm pretty disappointed there isn't an actual fix. I can't even set up a help ticket with MS because my console is "out of warranty". I've had the console since launch and it shouldn't show signs of wear, especially for what it costs. I've never had an Xbox go bad so fast (I'm currently running off my old OneX and it still chugs along); maybe I've just been lucky.

Any suggestions that I haven't done already would be appreciated. Thx.
