This is a bit of a hand-waving guess, but looking though the log, I see:

The "device als" is probably referring to the ambient light sensor, and in most MacBooks from this era (not sure about the 2019 16" model) it is in the display, near the webcam. The fact that you mentioned the camera not working is another hint. You may have a problem within your display assembly, or an issue with the connection between the display and the logic board, both of which could cause issues with the camera and ambient light sensor. [post|757316|This issue|new_window=true] seems similar though with a slightly different model.

The first thing to try would be re-seating all cables associated with the display assembly, as shown in [guide|135189|this guide|new_window=true]. If that doesn't do it, you may need to start replacing parts. I'm not sure if the display ribbon cable is replaceable in this model, but that might be a good thing to try before replacing the whole display assembly.
