Why Cant I play Forza Horizon 5 after I reset my PC?

Hallo SlappyMagoo , and everyone

Forza Horizon 4 - Teredo service problem on PC.

Read this if you have a Xbox Networking problem on your Windows PC

Message : 'Teredo is unable to qualify' , and 'Service Connectivity' is blocket in Xbox Companion Console.

For everyone who follows the troubleshooting steps on https://support.xbox.com/ , when you c'nt play Multiplayer an Xbox game on PC.

It can helps when you :

Reset your Modem/Router after each step, and see of the problem is gone.

I followed the steps 5 and 6 for solution the Teredo and Service problem, and after that, I reset my Modem/Router.

Now I was able to play Multiplayer in Forza Horizon 4 on my PC.

Then if it is not needed why i still can't access myltyplayer after doing everything you told me (i am from pc and i installed forza horizon 5 from steam)

Yeah Forza Horizon 5 and Starfield reinstall for me upon restarting my PC every time. I'm not sure if this is related, but I had FH5 and SF already installed on a different drive when I reset my PC recently, and don't think I re-downloaded them after, it just found them. I'm tempted to do a complete reinstall and not bring any games over this time, but no idea if that's why.

My Game Is in that list, but I cant find It in Xbox app, it's forza Horizon 5

Yes. Other games are OK.

Forza horizon 4 is OK too. But I bought it.

And Forza horizon 5 uses Game Pass.

I can start Forza 5 on my PC, can not start on Xbox serious S.
