So far haven’t been successful in finding anyone with a similar problem to mine. Before officially even streaming I noticed that the program would shut down if I tampered with browser source. I found a way around it by just using window source as that worked fine. Then recently learning about alerts I tried my hand at setting it up until I finally tried to add it to the stream only to have it shut down in the exact manner.
FYI, it was already closing before I signed into and linked my accounts to twitch and set up re.stream.
I saved an exported overlay file for my set up, then uninstalled only to have the problem consist after installation again.
Also no issues with streaming/recording.
