Core Server 1.7 crashes on start-up Windows 10

[Gareth_Brown]

Thanks I’ve got the logs, it’s roughly the same issue as:

Roon v1.7 “windows-10-object-reference-not-set-to-an-instance-of-an-object”

I am using a Microsoft Surface Pro 3 (i5-4300U, 128GB SSD) as Roon control PC. After updating Windows 10 to build 1903 Roon has stopped working. When I launch Roon (v1.7) I get this error “windows-10-object-reference-not-set-to-an-instance-of-an-object”. I checked the log file and it mentions openGL, so I tried to find if there are updated graphics drivers available for my Surface Pro 3, with no success. Below is an excerpt of my log file, in case it may help with solving my problems and …

I’ve tried looking for updated Intel drivers again, but I don’t think this machine will run it.
