OK.
Lets dive into it.
You have only 8GB of RAM and you need at least 16GB.
Monitor capture has to be on it's own scene. It casues issues with window or game capture.
You can safely reduce the sample rate of the Digital Audio Interface (USB3.0 Audio) to 48Khz so it works better with the low resources you have.
And this is your issue with the camera:
15:56:17.455: Error decoding video
15:56:17.455: DShow: Run failed (0x800705AA): Insufficient system resources exist to complete the requested service.
Check for updates on everything. Specially drivers. And the app most cameras comes with.
If problems persist, scale the resolution to 720p. Or go for 30fps.
Finally, you have a kind of old computer and you installed win11 on it. You'll be better with win10 fully updated.
