Uncaught thread exception

[netpro25]

I was wanting to be able to view the camera on HomeAsistant to then be able to see it on my Echo Show, however after setting up substreams and mjpeg streams I'm now (randomly) seeing this error in the logs. Do you need anymore information for troubleshooting? Is my config off?

Here's my config
