No menu path for VM and my plex VM seems to be gone. WHat happen?

Did you read the release notes? The vm backend changed and you have to recreate your vm with your existing zvol

Edit:

Manual Migration Required
Due to configuration incompatibilities between the previous libvirt implementation (TrueNAS 24.10 and earlier) and Incus in TrueNAS 25.04, existing VM configurations do not transfer automatically during the upgrade. However, TrueNAS retains storage zvols, allowing you to manually recreate the previous VM configurations and get them back online.
Instances are an experimental feature intended for community testing only. Users with production VMs on TrueNAS 24.10 should not upgrade to TrueNAS 25.04 until after this experimental feature stabilizes in a future TrueNAS release.

Well I did but I guess I did not fully understand. Can’t seem to get it running again, oh well, I will keep trying or forced to switch to app and re-config stuff

In addition to the Manual Migration Instructions in the release notes, you might want to to take a look at the 25.04 Instances documentation as well: Instances | TrueNAS Documentation Hub
