I am having trouble debugging an error that happens when I attempt to send video input to a Livekit agent. I'm using the "agent-starter-react" React demo as the frontend to a Livekit Python agent I created. When I turn on my camera or share my screen while talking to my agent, the agent immediately crashes and exits the room. My agent logs the following when I share my screen: "livekit.agents - process exited with non-zero exit code -4". How do I prevent this from happening?
