After spending a lot of time in this over 3 days, I have landed at a Debian install. I was having all kinds of issues with OBS in Ubuntu Studio regarding browser sources, Aitum Multistream, and Streamdeck with standard OBS install, PPA install, and flatpak install. Ended up dual booting to test a straight Debian install and things are working. Was able to stream fine with the nouveau drivers but afterward got the NVIDIA proprietary drivers installed. /6
