Anecdotal notes:

This laptop has severely downgraded after updating to Sonoma 14.1+

• I noticed the Touch bar stop lighting up a few days ago and also noticed my laptop crashed every time i put it to sleeep

• Just today I wasn't able to login, the laptop would get stuck after entering password. I kept noticing the Touch Bar flash which is what makes me wonder if that is related

• I was able to login after countless restart cycles

When I logged back in I saw the attached report for "Your computer was restarted because of a problem."

I'm happy to share the full report if that's helpful. At this point I am at a total loss. Would appreciate any and all help. Thank you

On your M1—

The best you can do if you have an issue— equivalent Shut down, close the lid 30 secs+ , reboot as normal.

If no resolve try SafeBoot Use safe mode on your Mac - Apple Support to sort anomalies.
