Xbox One X achievements not unlocking

I'm baffled by this one as I've used online guides for fixing, called support, and tried community experts to no avail. As best I can tell, these are the facts of my situation:

• I recently started playing xbox one again as a way to stay in touch with friends during these trying times. I had not played in a few years prior. I subscribed to xbox live and game pass, playing a few games. I was able to register achievements.
• I upgraded to an xbox one x. I downloaded my profile to the new console, downloaded a game pass game, and was again able to unlock achievements.
• I lent my old xbox console to a friend. While I was playing on my new console, he started up my old console, which contained my profile. It automatically logged in as my profile and kicked me out of my profile on my new console. I took back my login and
  my friend removed my profile from my old console. Since this time, I have not been able to unlock achievements on any game under my profile. This was 13 days ago

As attempted remediation steps, I have:

• Removed my profile from my new console, power cycled, and redownloaded my profile.
• Downloaded new games and performed actions which would unlock achievements.
• Refreshed my network and internet connection.
• Restored factory default settings on my new console.
• Determined that my Xbox Live connection is functional throughout.
• Checked True Achievements and confirmed nothing was registering without my knowledge.

The only other advice I was given was to reach out to the game developers, but this issue is across every game I play and many developers. It seems far more likely that this is a local issue than that every developer is experiencing the same issue with me,
specifically. What other actions might I be able to take to resolve this issue?
