Xbox Series X restarting a few minutes after playing a game

XBOX Series X, newest patch....sound cuts out minutes after loading. Restart the game and it works for about 2 minutes then cuts out again. It is only the Marvel Avengers game and it is new after the Tachyon rift patch.

It’s Xbox series X and it happened every three or two minutes Xbox did restart even if I don’t play

I have the exact same issue - Series X keeps crashing when trying to play with my daughter on PC. She has no issues or crashing, just me after a few minutes of being in the convoy.

I've had recent issues with noise and disc drive not being recognised on my Xbox Series X and the only way I found to stop this issue is to do a Full shutdown of the console and restart.

Settings>System>General>Power...>Full shutdown.

Its worthwhile removing power cable from console for a few minutes after you shutdown before you restart.

Annnddd it's back - but now flipped.

After the fix (thank you @Smwutches), everything was working well on both my Xboxes. We've been playing them both daily since December 23rd without any issues.

Today both my kids and myself played my Series X repeatedly without any issues - bouncing between both Game Pass and purchased games.

After my kids finished playing, I took over and was playing my Series X, but had to soft restart it due to a game (The Division) crashing in the load screen. After playing it for a few minutes, I closed it out and went to play a Games Pass game, only to get the dreaded "The person who bought this needs to sign in or go to the Microsoft Store". I even tried games I'd seen my kids play a few hours ago with no issue - now they won't launch and instead give this error. I also tried to simply do some Cloud Gaming - although I could launch the Game Pass game, it errors out when I try to launch via Cloud.

I confirmed that the Series X is NOT checked as the Home Xbox, and the Xbox One IS checked as the Home Xbox. No difference from where it was when we last solved this issue.

Any clue what is happening here, how to fix it, and avoid it from happening again? This is not only frustrating, it's a bit confusing that it seems to be randomly happening.
