After a little digging I found the likely culprit, it's a known issue with AMD
AGESA and the Linux kernel compile option 'CONFIG_CRYPTO_DEV_SP_PSP:

Quote from the RedHat Bugzilla:
Good news, I have received a reply from AMD regarding the issue after
submitting further information as gathered above and from other sources.

It would appear that the BIOS/firmware is advertising it supports SEV, when
in fact it doesn't. We currently don't have a timeout associated with the
SEV commands and so the module load is stuck - which would also explain the
KVM issue.

The current approach is to add a timeout to the kernel that stops things
sticking forever and submit that to the current stable releases.

A fix is also underway, but it will take a while to reach Tumbleweed or the
Leap stable kernel probably:
