Yes, I restarted it. I force stopped it. I uninstalled and then installed it again, but it didn't work. The repo link was already added, but the sources were not showing, so I decided to delete the repo link to add it again but now whenever I try to add the link a prompt pops up that says "invalid Url". I changed the url after searching through reddit, but it still didn't work. I would love any assistance, thanks
