R Session Disconnected (Only one browser may be connected at a time)

Referencing this post as I'm having the exact same issue and I didn't see a solution posted for this: R Disconnection Issue

I have tried closing the processes manually via the task manager but I continue to see this infinite loop of an error message saying "R Session Disconnected", giving me a button to reconnect, and then showing the same error again. I've tried uninstalling and reinstalling RStudio. I don't have multiple instances of RStudio and I'm not even using a browser to use it. Out of ideas!

I solved it by deleting my AppData for RStudio. Hope this helps someone
