I am also facing the same issue. I tried logging into my MacBook M1 (Ventura) this morning and it wouldn't let me past the login screen. Also it won't show the question mark which would usually allow me to reset password, which I haven't changed btw. I then booted up into recovery mode and tried to reinstall Ventura but I get an error message in a pop up dialog that says "Recovery is trying to change system settings. No administrator account found". Completely baffled! Any ideas how to fix. Now I am effectively locked out of my macBook.
