You can also run in safe mode for a while to see if it still happens

I wonder if Android is not trying to learn which brightness you “like”.

Do you also have this problem if you deactivate the automatic brightness ?

Had this problem in the beginning, too. But everytime when the brightness jumps without any reason, I manually set it back.
After two days the adaptive brightness logic learned about it, obviously, and the problem was gone.
