Since the latest 12.2 Monterey update my iMac can't go into sleep mode. After ± 7 seconds it wakes up again, staying awake forever. I tried rebooting, but even before any user logging in it's the same.
Thanks a lot for a good idea!

Are you using a Logitech mouse?
PS: In the meantime I tried booting in safe mode, without logging in: same issue. I click "Sleep"; for a second it seems like going into sleep mode, but immediately wakes up again.
No. Only Apple Bluetooth mouse & keyboard (I used my old Apple usb keyboard to reboot in secure mode).
iMac wakes up from sleep – even with no user logged in
