In updating to beta 4, Big Sur seems to have locked the drive with FileVault. It is trying to retry the update, but says my drive is encrypted and to enter the password. Problem is, my admin user password doesn’t work and neither does my iCloud password. I’ve tried terminal tricks from the recovery partition for hours with no success. I 100% did not set a FileVault password at any time manually, and this isn’t a case of a forgotten password on my admin account - I’m sure of it. It’s the same one I’ve used on my Mac for years and I’ve entered it with success hundreds of times in Big Sur before this update bricked my install.
When I go to unlock my other partition, Catalina, it allows me to choose an associated user - my admin account. Big Sur drive does not even give me that option.
