I'm sorry. But still doesnt understand what the issue is. In the log I see you try to capture a vp9 table. But this fails, because ffmpeg is not in your pinballx directory.
If nothing is working on pbx, try step by step. Not getting all the systems up and running, but do it 1 by 1.
Start with the easiest (like fx3). If you sorted out how it works, you can setup all systems.
If you got issues, please provide a brief description of your setup (all hardware, settings in windows). If you got an error during startup, please attach a screenshot, or the message.
