New M1 Macbook Pro locked spontaneously and will not unlock

I was working away on my new Macbook Pro, using both mouse and keyboard pretty constantly, when the screen suddenly locked.

I thought "Interesting glitch", and I entered my password to unlock the screen.

It accepted my password, but the screensaver is still running. I can move the cursor around the screen, and it seems to be accepting keyboard input, but all I see is the screensaver.

The first time I pressed the "Mission Control" button on my keyboard, I was able to see my screen again,

but whatever my next move was put me back at the screensaver and that button no longer has any effect.

I'll force a shutdown, and am sure it will be fine after that, but I want to get this information out there.

You can file a bug report here—Apple Feedback http://www.apple.com/feedback

Just happend to me too. Freshly installed yesterday.

Same here, running it with the lid closed on an external display. Apple mouse and keyboard and it keeps locking the screen randomly.

Yup, just done that as well via the Feedback Assistant app.

My wife's M1 MacBook (non-Pro) is having the same issue. I hope they fix this soon, it's immensely frustrating.
