Hi Jim, I have also now run into a similar issue, I tried the steps in your workaround (with VIPM 2020.3) and it is looking for installer media here:

- Repairing LabVIEW from NIPM
- Repairing VI Package Manager
This is what's in my installer build spec:
And the only thing it's complaining about is the "VI Package Manager Runtime Engine":
