So going TrueNAS Core 13.0U6.4 migrate to TrueNAS Scale 24.04.2.5 via a fresh install and then restore TrueNAS Core config file, and then upgrade to 24.10.1. This meant that I no longer got the “Failed to load datasets ‘path’” error.
The VM issues turned out to be renamed NICs inside the guest operating systems, and a file permissions issue to an ISO for Windows VM.
After upgrading to 24.10.1 I was able to use CMD to setup the bridge on top of my LACP lagg. I was still unable to use the UI as it would not let me unassigned the IP from the lagg, nor would it let me add it to the bridge as it said it was in use. This was even with all network service stopped. 24.04.2.5 would give me the same errors from CMD and UI.
The only outstanding issue I have now is

I didn’t manually scrub the USB Hynix SSD from the old 24.10.1 install. I let the installer for 24.04.2.5 just overwrite it, which going by the JIRA ticket above causes this issue
I might attempt a reinstall → restore config at a later date which going by the JIRA ticket is the only fix for this. But for now the system seems to be working and I don’t have any issues rebooting the server, so leaving it for now.
I hope the above helps anyone else trying to migrate / upgrade to 24.10.1
