Starting with an early version of Big Sur and continuing in Monterey, I get a "System Extension Error" message on startup. Always. No indication of WHICH extension/extensions is/are causing the problem. Going through the Security & Privacy System Preferences reveals nothing unusual.
Is there something I can check in Console or with EtreCheck that will show where the problem lies?

Suggest downloading the Application Etrecheck directly from a well Respected ASC Contributor.

Run the application with Full Disc Access ( Security & Privacy - Full Disc Access ).
It will take a Snap Shot - both the hardware and software.

The The Built in Security is all that is required.
The Etrecheck report confirms what you have already concluded "the time for a true nuke and pave has arrived. " would be a good staring point. There after, selective installations of Application directly for the Developers would be a good start.
The Extensions are listed in the sections titled, "System Extensions" and "Kernel Extensions"
I was going to copy/paste the list, but there was a metric ****-ton of them. Is there anything you avoid installing?
You might have more system modifications installed than you have system.
It might be that one of them was not updated for Monterey, but still sort of works.
It is asking you to allow it much as you did when you installed it, but that doesn't seem to be showing up when you go to Security & Privacy.
I don't know why that error dialog doesn't include the name of the extension except that the name can be something entirely cryptic which may not clarify the situation at all. A "clean" name might be in the form, "com.objective.littleSnitch". But, it could be just about anything the developer decided to use like, "org.nothing.jumbledtext.glomulator".
Hahaha. Yes, I was surprised, as well. Shouldn't be, I suppose, as the system has been migrated for years and years. I suppose the time for a true nuke and pave has arrived. Thinking there may be more than one extension causing the problem, maybe more than the error message can list.
"System Extension Error"
