I've tested a UMC1820 (which I don't own) with stock driver 4.59.0 and tools from Behringer (
https://www.behringer.com/Categories...0B2J/Downloads ) on my HP2760p running Windows 10 Pro x64 1909, which I use for live performance with Reaper and Arturia. Similar CPU, i5-2540m, Sandy bridge. It just works.
I still think you've not installed the graphics driver correctly, or have not installed chipset drivers. when I kicked out the driver linked earlier, and returned to Windows 10 stock, it got exactly the symptoms you described.
Anyway, as you've given up already, there is no point helping any more...
