I think that all the info you provided is invaluable. According to System requirements for Microsoft Defender Application Guard (Windows 10) - Windows security | Microsoft Docs , WDAG can also be installed to Win10 Pro and Education, so statistically it is expected to see reports from these users too.
Since WMware and MS are keeping an open channel of communication we expect they will eventually sort this out.
However, I expect that any program that installs its own drivers (e.g. a virtual DVD drive or an advanced audio software) as well as hardware driver installation programs themselves may be facing their own problems too, so maybe this thread in the future will appear in net searches, informing users that these may be related to a recent WDAG installation they did.
