Thank you for your replies and ideas for solution.
Since my problem we started a new league without crossplay because we blamed the problem on the crossplay servers and now unfortunately 3 players (PC) can't play anymore.
last week we had the same problem with the warm-up round even though we had crossplay disabled. so the game has a massive problem with desync. Luckily we were able to deactivate the warm-up round afterwards and restarted the session. Without the warm-up round there is no problem with the warm-up round (which is not the solution to the problem, just a workaround).
The host of this race crashed and was forced to leave the session by the game. The host was migrated again and the next big errors happen during the host migration. 1-2 players are still visible and physically in the race, but are driving in their own session. These 1-2 players are driving their own race and the positions and SC phases do not match the other drivers. And when they are invisible to others, you crash them in corners in their game. DESYNC.
Yesterday we had another race and the same error occurred with the desync after the host migration.
I also have a report code from this session: SECK-EPCH-BAKR-SHEG.
If you need the report code to be able to trace a session error, then this code should also be displayed somewhere in the results window or in the ranking list or something else. During the session, hardly anyone will go to the menu and photograph or write down the code. The way it is solved now is not really practicable.

LukSte9799 had the problem with desync and so he was able to overtake me in SC because he didn't see me in his session. In his session i was still in front of him but everyone else was sync with the new host.
@EA_Groguet tagging for session code.
