Centos 7 to almalinux 8 fails to boot

I ran used this procedure

after addressing the inhibiting/high issues in the report and getting a clean report, it appeared the upgrade was successful. Didn’t see any errors. However after the reboot and the upgrade procedure finished, the system fails to boot into almalinux. Looks like something got messed up with the update but don’t see any errors.

I have installed almalinux from scratch on several other servers (same hardware). No issues there

Anyone have a clue?
