Looking at your log file, there a lot of these errors:
20:08:08.333: ==== Recording Start ===============================================
20:08:08.334: [ffmpeg muxer: 'simple_file_output'] Writing file 'C:/Users/Lord Bacon/Videos/2019-11-06 20-08-08.mkv'...
20:08:10.742: [game-capture: 'Game Capture'] attempting to hook fullscreen process: ApplicationFrameHost.exe
20:08:10.742: [game-capture: 'Game Capture'] cannot capture ApplicationFrameHost.exe due to being blacklisted
OBS sees ApplicationFrameHost.exe that owns the full screen. Since OBS black lists it (can't be trusted, possibly hacked, other reasons.), you get a black screen.
Its best to:
- Remove the game capture source
- Restart OBS
- Use Display Capture when running Universal Windows Applications (UWP) obtained from Microsoft Store
- Run UWP application in window mode
That will avoid the mismatching in process identification and window mode/title when using Game Capture
