Forza Horizon 4 on XBOX & PC

Hello all,

I had a problem with my FH4 profile and the synchronization on XBOX & PC.

Description:

I use FH4 over Game Pass on my XBOX and my PC. The PC runs on the Insider Version from Win 10 and it's up-to-date. All drivers and WS-Apps were updated, so plz no comments about updating.... So, when I play on the XBOX and went to the PC, FH4 starts and
say, it will synchronized with the cloud or wait while the XBOX hasn't finish the synchro with the cloud. (Info: the XBOX runs allways on, same the PC, the become a restart every morning or after Update, both had connection to web). When I select try again,
nothing happens. I can click on this button 100 times - no change. When I select syncronizing the cloud game, on PC I become the selection to use the older prifile on pc or the newer profile from the cloud. But: the cloud game is not the last game from the
XBOX. I can see at on the credits and I lost cars from wheelspins (f. e. I won the Ford Crown Victoria on Wheelspin, I use it, made a design - and I can find the design in my catalouge as first entry - but the car isn't in my garage). The problems had another
indicator - since a few weeks, I can't see the pics from a few cars in my garage (f. e. McLaren P1, Mercedes G63 6x6, Mercdes CLK GTR, Alfa 33S or AMC Rebel).

What I try to fix:

Reset the App on PC and after no changings reinstallation. Reset XBOX complete. No changing. All systems and apps run on latest builds, everything is up to date. I had no changing on network or internet connection. The useing from both platforms runs without
problems on FM7 & FH3.

And now I need your help. Any ideas? I dind't want restart again... I play FH4 since release and now I'm going to the third run. It's a profile with a lot of work on it and I didn't want loose it.

THX
