I ran across the issue of my webcam not displaying on "LogiCapture" but the webcam would work totally fine on any other camera apps. After double checking that the permissions were on, and uninstalling and reinstalling my device drivers, I still had no luck. Eventually I managed to figure out the solution and I hope this tutorial provides you with the correct solution to your problem as well.
