Forza horizon 5 From Xbox to Steam

Thank you for your response. If you want to play the game Forza Horizon 5 on the Xbox app, you will need to purchase the Xbox game version on the Microsoft Store:

Since you have purchased the game on Steam, you can only play it on the Steam Launcher. You won't be able to find your Steam games on the Xbox app library as they have their respective launchers.

Remember that Steam and Xbox PC are 2 different gaming clients.

On Xbox, it's Forza Horizon 5. On Steam I tried Payday 2, on Epic I tried some random game I forgot.

No only this game Forza Horizon 5, other game Minecraft working normally, game2 from steam, EA, Ubisoft, Epic all normally i play.

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)

Forza Horizon 5 does NOT have any announced or planned cross-progression from Forza Horizon 4. Aside from Forza Horizon 1 (which did had loyalty rewards for Forza Motorsport titles), there has never been cross-progression for Forza Horizon titles. You always had to start fresh with each game.

And about Forza Horizon 4: the lack of possibility to use the same save between Steam and Microsoft Store comes from the technical point of the each game. Both use a wholly different methods of saving which is far too much work to make them co-operate, ESPECIALLY considering that Forza Horizon 4 is way past its' prime.
