Viewer on extended display is white

[hardevs]

Currently running into an issue where the Viewer on the extended display is just white. It remains white screen while I'm selecting Bani on the laptop. I have reinstalled sttm multiple times on this laptop running Windows 10. It was working last week, not sure if any windows update might have caused this. Any additional pointers? How is the communication occurring between the Viewer and the main thread app? Is it through HTTP, socket or some other protocol? I'm just looking for additional pointers. I will look through Event Viewer logs later. Does STTM have any direct logs? If so, what's the path?
