When running Episode 2, I am unable to answer the conversation multiple choice questions and thus cannot proceed more than a few mins into the game. The prompt appears attached to my left hand, but no input that I can find allows me to highlight or select a response.
I am using Windows 10, an HTV Vive Pro headset, and Valve index controllers. I can try with the Vive Pro controllers if you need, however Episode 1 worked with the Index controllers so I assume Episode 2 would as well.
Also, now that I've run into this issue in Episode 2, I can no longer select dialogue in Episode 1, so in that game too I am unable to play.
