I think you need to reinstall OBS as you have some reference library assembly files missing from your current OBS installation:
16:06:37.570: Required module function 'obs_module_load' in module '../../obs-plugins/64bit/libcef.dll' not found, loading of module failed
16:06:37.576: LoadLibrary failed for '../../obs-plugins/64bit/libEGL.dll': The specified procedure could not be found.
16:06:37.576: (127)
16:06:37.576: Module '../../obs-plugins/64bit/libEGL.dll' not loaded
16:06:37.603: Required module function 'obs_module_load' in module '../../obs-plugins/64bit/libGLESv2.dll' not found, loading of module failed
Also, your colour format is set to 601, which is really only for below 720p resolutions and is more for compatibility with devices that cannot use 709 colour format:

Another thing, not sure if you are using Monitor Capture to record/stream games/windowed applications, if you are then you should consider using Game/Window Capture:
Game capture grabs the frame directly from the graphics card for OBS to encode before sending it back to the graphics card for final rendering of the frame.
Monitor capture has the graphics card write the frame to system RAM (Which is really slow to write/read from) before OBS grabs it to encode, then sends it back to the graphics card to render for final output.
If you want to use Monitor Capture, you should create a scene for it by itself without any other capture methods included in that scene.
