Not sure exactly how...
But somehow I have a remnant vMix Replay-B input that cannot close or be removed.
I was adjusting Output settings requiring vMix to relaunch (from 1280x720 to 640x360).
Prior to that, I had set-up a single SD camera (720x480) in the Instant Replay application but it did not re-launch with the new settings...
Can't remember the error message but it may have been the same as below.
However, the single "un-closable" vMix Replay B input did launch and there is no way to get rid of it.
Re-inputting the single camera Instant Replay appears to be successful but the remnant input (although showing the same image as the new vMix Replay B input) appears to be an independent input.
Closing out the Instant Replay input puts vMix in a never ending loop with the error message:
"Object reference not set to an instance of an object."
