Session gets detroyed by invalid playerstate

I will explain the process right here.
The player makes a server a client joins the server when they are ready, the game starts so that is the part where the servertravel occurs. while traveling the client disconnects. I didn’t have this problem in 4.16 but in 4.17 this problem occurs.

I hope somebody can help me with this because I am stuck now : (

I have also reproduced this problem and that worked fine. Migrating also doesn’t help.
And also I have upgraded this project from 4.16 to 4.17

The gamelogdisconnecterror is the log from the client and the other one is from the server.

I can see that there is something wrong with the playerstate but i dont know what.
Regards.
