My Premiere Pro 26.3 uninstalled itself

My Premiere Pro 26.3 just uninstalled itself yesterday, and today Premiere Beta 26.5 downloaded itself. Good thing all the settings were saved, I just uninstalled the "beta" and downloaded the stable one. Why did this happen? What's going on here? What should I disable somewhere so that things like this don't happen without my knowledge? I can provide relevant reports if needed.
