Unplayable game

Thank you for the reply, I do believe the main issue is that my account might’ve gotten targeted by the security systems. There’s a new measurement that started working since you put the repeatable 10 x 85 sbc, it targets the squad building to limit the submissions of the sbc, however this is also affecting normal play features such as rivals, champions and gauntlets.
it’s not related to the first issue  you mentioned and for the gauntlet I cannot use my players and I do need to edit the squad before launching a game, and after spending so much time doing that and attempt to start the game it just disconnects me from ultimate team and all progress is lost.I hope you find a solution to fix this issue because meanwhile the game is unplayable for me.

Hey dhaker_wolf​,

If you are running into an error starting a Rivals or Champions match, it could be related to an EVO applied to one or more of your players that granted a 5th PlayStyle+ that's not working correctly. Removing or replacing the EVO should help. 

Other players also reported this situation recently, and our teams are investigating.

In the meantime, if you also run into an error submitting an SBC, is it a single SBC or any SBC you're trying to submit? If you have submitted many SBCs before this error started, please try taking a 24-hour break from attempting to submit new SBCs. You might have been targeted by our security systems against bots and automations.

For the Gauntlet mode instead, please check if you can start a match without editing your squad.

It might also help to delete the corrupt files following this guide, including the Online squad updates and Personal settings 1 files, and to delete your squads on the Companion app or the Web app, leaving an empty one as the active squad, before you try to start a new match in-game.

Let me know how it goes.
