Hi @aj265
What worked for me was using the „DriverStoreExplorer“ tool (it is freeware, you‘ll find it via google).
Long time ago I did it, but if I remember well, I just installed the Google Android USB driver (link in the Herelink docs section) with that tool and it worked then immediately.
(Like you I experienced that the Windows 10 device Manager did not let me deinstall the initial driver or install another driver.)
You may give it a try.
