Your network connection seems to be having trouble keeping up with your bitrate. You should check that you don't have firewall software that is limiting your network performance, or possibly contact your ISP, and double-check using TwitchTest that you're using the best ingest server for you.
Other items of note:

Increasing audio buffering is usually a sign that a system is being overloaded.

You've got a display capture, a game capture, and a video capture device in the same scene. I can't tell if the video capture device is a webcam or not. You definitely should not have a game capture and a display capture in the same scene as they interfere with one another. If that source is a capture card, you should have separate scenes/scene collections for those items. Just hiding the items doesn't stop them from operating.
