I have a M2 Mini driving a studio display. I set the Lock Screen settings to turn display off after 3 minutes.
Display won't turn off.
Then I turn off Bluetooth (connect keyboard and mouse via cable) and the display sleeps as it should.
Turn Bluetooth back on => no sleep.

What make and model are the keyboard and mouse..?
This sounds like a faulty keyboard key or a faulty mouse click/sensor, that is creating continuously input activity and preventing display off.
To figure out which one, you will need un-pair them from the bluetooth one at a time and test.
Another thing that I would test, is "Turn display off... at 10 minutes instead of 3 minutes.
