OCLP Ventura Airplay to tv has sound but just a black screen help!

I have a 2011 MB Pro 13" that I know can Airplay mirror to my Roku tv because it was working great on Catalina, but when I upgraded to OCLP Ventura something went wrong. It says it's working on my Roku but I'm only getting sound and just a black screen?
Like something is blocking video.

I don't know if this is connected to the issue, but when I go to update OCLP it returns an error that it cannot mount. I also get the "upgrade to Tahoe" in software updates even though I turned them off in the settings.
Any fixes for getting the video to work in Airplay?
Thank you :)
