I was upgrading the OS on my spouse's 2019 iMac from Mojave to Monterey, but the install failed partway through. I tried to re-run the install twice, and it failed agin. Now, I just want to restore from the Time Machine backup just before I tried to install. But that doesn't;t work either.

A Time Machine Backup is very useful and can be used to Revert to Previous Working macOS
