Display won't stay asleep

Apple Magic Mouse that I've used with my previous mid-2011 iMac for 12 years. "Wake for network access" is off. I recently booted into Safe Boot as suggested in another post. I'll report back if that helped any.

I want to specify that I had my Mac Studio performing a large Time Machine backup with the display asleep. Only the display waking itself was the issue. Seems to have been fixed booting into Safe mode.

Well, Safe Boot may have fixed the issue. Display didn't wake up all the last several nights after performing a Safe Boot. I'll report back if Display starts waking up unexpectedly again.

Display connected to MacStudio hasn't woken from sleep since booting into Safe Boot.
