 FileVault has been buggy throughout the entire Big Sur development cycle. For maximum stability, disable FileVault before upgrading to Big Sur. Once you upgrade to Big Sur, bugs may make it impossible to disable FileVault and may make it impossible to unlock your FileVault volumes when applying updates or booting from the installer USB. (Not to mention, FileVault bugs may also make it impossible to open Terminal on the installer USB.) The best way out of this conundrum is probably to back up the entire Big Sur installation using Time Machine (Time Machine encryption, unlike FileVault, appears to be stable), erase and reinstall Big Sur, and use the Setup Assistant to restore the Time Machine backup.
 
-Upgrading from a Catalina installation which has been patched using dosdude's macOS Catalina Patcher seems to result in an unstable system. The instability is not fixed by running the Big Sur installer again. So far the only fix seems to be similar to the method for disabling FileVault: Back up the entire Big Sur installation using Time Machine (Time Machine encryption, unlike FileVault, appears to be stable), erase and reinstall Big Sur, and use the Setup Assistant to restore the Time Machine backup -- in my own testing, this does appear to correct the instability.

 Time Machine backups must be restored by first performing a fresh Big Sur installation and then doing the Time Machine restore from the Setup Assistant. Attempting to do the restore from the installer USB fails. I do not yet know if this is inherent to Big Sur, inherent to the patching process, or a bug in this patcher.
