The following problem: I'm playing GTA 5 Online on Xbox One X. I'm constantly alone in the session after a few minutes, even though 10-15 other players were online before. From now on, everyone will leave the session. Then I'm asked to find a new session and the same game happens again. I tested the multiplayer mode in the settings and all without problems. The NAT is also open. GTA and the Xbox is up to date. I'm getting really desperate. Google doesn't get me anywhere.
I don't know how you can specifically solve the problem, but you can work around it by first going to GTA5 Story Mode and then going through the options in a closed friend session. You can find more information on YT.
I do not have "friends", I want to be in a public session. Youtube and Google only tell me how I can get into a public session on my own, but not how I prevent it.
Otherwise try to reinstall GTA
