Montery 12.4 and command line tools update not accepting my password.

I've been trying to clear the red software update icon for two days. First it was just the command line tools update. I kept getting that outrageous, ridiculous "Not An Owner" error. Since I paid $1200 for this machine I'm pretty sure I'm an owner. Now Monterey 12.4 is added to the update list. I can finally get to the little window where System Update requires a password. I type it in and the window shakes like I entered incorrectly. (But no error message confirming.)

I've rechecked the password by logging out of the machine and signing back in with it. No problem there. So I didn't forget my password and shouldn't have to reset it. And I've typed it into the System Update window that's rejected me at least a dozen times. S L O W L Y. So what do I do now?

My machine is a 2020 M1 MacBook Pro. I wish Apple would quit rolling out updates I can't install. Thanks for any help.
