flash of light under menu bar when lifting open closed MacBook Pro 2019
about a month ago while I was still not upgraded to Monterey and still using mohave my MacBook suddenly started to flash a bright light behind the menu bar on the upper portion of keypad when I opened it up to use for the day. I have since upgraded but it still happens. also as soon as the Monterey 12.5.1 was installed I came back to use the computer a bit later and the fan was racing and it was very hot. I had not been using it. not sure if this is a common problem, I have googled the flash of light under menu bar and that does seem to be a problem with these computers going back even several years but the "fixes" were old posts and I'm not a computer nerd and don't have the knowledge to disable/reinstall/reboot apps or systems or whatever had been suggested at that time. can anyone shed any light on this situation? thanks. ps. I do use Avira scan and I have no virus issues.
