Old issue, new issue, what changed?

Boot into Internet Recovery (Option Command R) and from the dropdown menu: Utilities>  Disk Utility> run the First Aid on your Macintosh HD (and the "Macintosh HD-Data" volume as well if Catalina/Big Sur/Monterey) If errors are found and repaired, run again until no errors reported.

Disk Utility>View>Show All Devices The best sequence is —

Volume level

Container level

Parent drive
