apple macbook pro a1286 boot looping after update

Option key but won't boot to restore from USB or time machine.

Gets to logo and status bar completes then goes white then reboots again. This qualifies as a significant problem when it occurs given its clearly disruptive nature and it would be good to get to the bottom of this. When trying to boot back up it is now stuck in boot loop.

The only remedy is a complete restart of the machine.Logging in and out of the macOS session does not help. The audio loop stops when the presenter leaves the meeting but carries on exactly as before when they log in again and rejoin the meet.The audio loop stops when the presenter leaves the meeting but carries on exactly as before when they rejoin the meet. The audio loop interval itself is about 3-5 seconds.As in - the presenter's audio starts looping and this is quite obvious to everyone else in the meeting but not to the presenter. The audio begins looping about 20-40 minutes into a meet.The hardware is an M1 based MacBook Pro (13-inch, M1, 2020). I've had 2 instances personally in the last 3 months of the same issue.
