what is OS status error 22?

A "seal" is part of the Signed System Volume (SSV) in macOS Big Sur. Not being able to use the "Restore" feature is a known issue in macOS Big Sur. So, you need to erase the disk, install macOS Big Sur, then transfer data manually, or with Migration Assistant/Time Machine restore.

1. Turn on the Mac, (if off) and immediately press and hold Option + Command + R until you see a spinning globe.
2. Once you are in macOS Recovery, verify you are connected to WiFi in the top right corner.
3. Go to Disk Utility.
4. Select "View" in the toolbar —> "Show All Devices".
5. Select your main hard drive or SSD. This will either be the top, non indented hard drive. 
6. Click Erase, and input the following exactly: (If you cannot select erase on the main hard drive, erase the "Container" or “Macintosh HD”.)
   1. Name: Macintosh HD
   2. Format: APFS
   3. Scheme: GUID Partition Map (if shown)
7. Click Erase. If “Erase Volume Group” is shown, use that instead. 
8. Quit Disk Utility
9. Go to the reinstall macOS app.
10. Follow the prompts, and install on Macintosh HD.
11. Restore data using the method of your choice.
