Constant blackout and sleep (every 10-30 min)
 

This happened once before and stopped now it's started again.
Macbook air M3 (2024) into a Satchi thunderbolt with 2 LG ultrawides

The screen goes wonky then the computer goes to sleep. I'm chatting with support now and have had to send 3 crash reports so far in the last 90 min.

Anyone else getting this?
