Hey all, I apologize in advance if this problem has already been solved, but I'm having trouble with VirtualCam output. Everytime I try to launch VirtualCam, I get the "Failed to start output" error. I have reinstalled/updated the drivers for my GPU, and restarted every program involved as well as my machine.
Here's my log:
