Expelling demons from 2020 Air: when Disk Utility says to run against the Container (and more)
Monterey T2 bug - First Aid, unlocking disk, operation canceled - Do an SMC reset
When I tried to run Disk Utility on my 2020 Intel Air running Monterey I got:
Running First Aid on ..
Google found exactly one reference to this in a 2021 Apple Discussion post with a link to an Apple Support article that has since been removed ...
... That turned out to the known issue linked with the T2 Security chip (https://support.apple.com/en-us/HT203127). Resetting the SMC solved that problem as well as the original problem with the hard drive.
Resetting SMC (I used two methods) fixed the bug and First Aid was able to continue. (There are other problems, but at least this one was fixed.)
I don't know if this insanely rare or if Google simply isn't that useful any more (probably both). Resharing here.

Managing multiple Apple Store Apple IDs in Monterey: how to sign out and thus change default Apple ID for app update and purchase
There's a lot of complexity in Apple's software, but my nomination for the ultimate complexity is the web of undocumented and slowly changing rules and tools around Apple's Digital Rights Management (FairPlay) including rights to use media (music, video) and software (apps) for both individuals and family members.
I don't think anyone truly understands it all, not even Apple's senior developers. Sometime in the past decade Tim Cook said he'd fix the Apple ID problem and then things went silent. It's a nightmare. I remember when changing a phone number associated with an Apple ID could switch the ownership arrangement for device history (presumably a matching problem between disparate databases).
My most recent experience with this was trying to fix the default Apple Store Apple ID used to for Mac App Store DRM on my wife's Air Monterey account. It was defaulting to an Apple ID we used to share for iTunes purchases 10+ years ago. I've been slowly disentangling it for 4 years now and the rules change with each macOS/iOS release. Currently there's a bit more tooling to sort out who owns what on a Mac but it's obscure.
As far as I can tell the controls for this are now hidden in the App Store app. That kind of makes sense, because the rules (and Apple's DRM contracts) for movies/TV, music and apps are all likely different. You have to go into the App Store app, which can show the apps associated with multiple Apple IDs, then you have to sign out from the menu:
