Last week we had no electricity and next day the imac start with the message "you turned off your computer because of a problem". I see the monterey wallpaper and my login. After typing my password the system goes to my normal desktop.
The Problem is that this occurs every time I start the imac. Anybody have an idea to solve this problem ?

That message implies a Kernel Panic, presumably caused by the power cuts. Something has stayed corrupted so happening every boot.

I would start by booting to Recovery and running Disk Utility > First Aid.

You could also do a Safe Boot which clears some caches.

How you do those depends whether you have a Silicon or Intel Mac, but Google has the answers

There are some other things you can do like reset PRAM and SMC but these also depend on type of Mac.

If none of the above work you could re-run the installer from Recovery, without erasing first.

If that doesn't work, you would probably need to erase, install, migrate from backup, but don't think it should come to that.

Good recommendation - that thread seems to show it works.

Someone I know was successful in clearing the same problem using Onyx. I've used Onyx for years, but so far, haven't had this particular issue.

The OP should keep in mind that the System Volume is sealed, and this would *not* be a reason to reinstall the OS>
 
I don’t see the problem. That’s what is supposed to happen when you log in.
The problem is not the request for the password. OP's issue is the recurring error message that pops up on every startup BEFORE requesting the password.
 
Oh. I get it. I can’t think of a reason that message would persist across starts.

There is a setting in the user's Data volume that is checked when there's a Kernel Panic. It should be cleared after the first restart, but maybe the abrupt loss of power prevented it from being properly checked and written, so the System can't easily clear it. That's why Onyx, which can be told to clear all these settings, is so helpful.
