The BigSur update (the 11.6, and before 11.5.2) doesn't finishing (no refressh) on my MacBook Pro (13", 2020, 4 Thunderbolt 3 ports). Downloading, and after stopping.
The only solution is to delete all the data and rebuild the system again and again. I think this is not the right procedure.
Sounds like something went sideways...
You can try running the Disk First AID in an effort to get beyond your issue:
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) 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
