Motion Controller Button Inputs Not Working in VR Template

I’m having the same issue as above poster, my motion controllers are movement tracking however all inputs on controllers are inactive.

My configuration is as follows:
For simplicity of debugging, I’m using the VR template with Auto Receive Input set to “Player 0”. All buttons are correctly mapped. Furthering my pain is the fact that all of my VR Maps that I’ve previously created and have tested for correct button input play are all now suddenly not working. Projects that have I have developed previously with multiple levels and VR capabilities, are all suffering the same fate, no input control from the controller.

Lastly, when I launch any games from from my Oculus Library, like the Oculus First Contact primer game, the controllers DO work. I am thinking that the Unreal Engine install has somehow corrupted itself. I’m running the current 4.21.2 hot swap version. Help is most appreciated in this matter and Thank You!
