Mac powering off unexpectedly - due to iDriveDaemon ?

My new MacBook Pro M1 is intermittently (a couple of times per day) powering off for no apparent reason. Interestingly, my previous MacBook Pro (Intel) did exactly the same thing. I migrated everything from my old computer to my new one. This makes me think it must be a software issue. Here's what appears to be the most relevant log entries which are written just before it powers off.

I use the iDrive cloud backup service, and iDriveDaemon is part of that.
