I have the same issue .. I tried different hit and trial and it seemed to work once when I created a new squad with all new player which didn't contain any player [playing 11+sub+reserve] from the initial squad of that match from which this problem first started. and on keyboard as my input device. then only the match ended without an EA server error.

I need to complete "Jo" objective only 1 low driven left, why ea why … after this update you screwed me. is this what you take our money from us for.
what kind of glitch is this. who is gonna compensate for those lost hour and the objective card which I might loose because of this.
I cant play my main team cuz it will just show error after completing and winning the game. We need a fix fast.

[it also happened in previous iterations of fifa ]  we need a fix.
