Vegas Capture - Launches and I can see all of my devices but when I press the record button, Capture goes black and I have to right click and close the window. Sometimes it works fine and then it won't work. The sound recording is terrible with Capture so I try to record on a video track simultaneously and that works sometimes. It's completely random and very frustrating. I've used it successfully on this same set up in the past, it's just in the last month or so that I've been having this issue.

I've tried killing other applications, etc. and nothing seems to be a solid fix. Any thoughts on why it randomly just fails?

I am now in Vegas 21, but I was having this issue in Vegas 20 and thought the upgrade might fix it, but no such luck.
