OK - so all of my vm's are stored in folders outside of the install path. I uninstalled 17.0.1 and preserved the license and some other configuration setting when prompted. I uninstalled 17.0.1 ad reinstalled 17.0.0 - when I launched workstation my VM's were there - I ensured "Bridge Mode" was what Home Assistant (HA) network was configured for and then started the vm. When HA started it was on the correct network and all was well again.
This is definitely a bug in the later version and needs to be fixed.
