Upgraded vm version from 5 to 9 and now it wont boot

I upgraded my hyper v host from 2012r2 to 2019.  All my vms powered on and ran fine.

Two days later I used Update-VMVersion [computername] and moved my vm from version 5.0 to 9.0.

Now when I try to boot it, i get this error:

Failed to start.  Failed to get security info.
