[ovirt-users]oVirt Administration Portal will not load after upgrade to 4.5.7

I'm running oVirt in standalone on a Centos Stream 9 box. The VM Portal will load fine, but the Admin Portal fails with a 500 error. When I dig down in the server log, the error message is: Caused by: java.lang.IllegalArgumentException: MigrationPolicies has no value for version: 4.8 When I run engine-config -g MigrationPolicies I get results for version 4.2 up to 4.7, but nothing for 4.8. Is this something I need to manually add? One other piece of confusing info is that the console still lists the version as 4.5.6-1.el9. I didn't see any errors during either the yum update or the engine-setup processes, but I may have missed something. Any help you all can give me would be great.
