I have analyzed the WUDFHost memory dumps.
Can you confirm their timestamp matches when your machine was hanging?

I see a few things in them. DisplayLink driver is terminated when trying to retry initialization. I've created a bug report for engineering to look at that because, we should not have to retry in the first place. The fact that the dump is created when retrying is a known Windows 10 Anniversary Update limitation. Microsoft kindly changed their USB driver to allow us to retry on Windows 10 Creators Update to work around a hardware issue observed in very old hardware from a specific company.
But all that has no reason to hang the machine: terminating a driver is a normal thing. It should just somewhat gracefully recover.

I don't see anything about the Ethernet driver. Would you have more information on that?

Kind regards,
Alban
