Controller input freezing on PC

Before the TOTYs on Thursday 15 the game was running with no problem for about 2 weeks. When the TOTYs dropped, EVERY match became unplayable. I'm running EA FC 26 via Steam and using a DualShock 4 through Steam Input. Every 5-10 seconds, the controller input freezes for a few seconds, leading to the player to keep running and not pass or shoot, or staying still. This happens on Rush, Rivals, Squad Battles, EVEN IN MENUS. I've tested both controllers I own (both DS4s), and my keyboard, and their input still gets frozen or delayed like that. I've tried with other games and controller testing programs, but no, this only happens in this game.
It's literally unplayable, there's nothing that fixes this problem. Way to kill the TOTY hype, plus with these tight time constraints on objectives and evolutions, this has gotten really frustrating.

I have an option enabled ingame to show the inputs in a little controller on the upper right part of the screen, and yes, it's getting stuck, it's not even input delay (would be visible with a delay between white and green inputs), the buttons and joysticks simply don't respond for a few seconds out of nowhere.

It's insane that SINCE release I have only been able to play this game without game breaking problems for only 2 weeks.

And NO, I can't disable Steam Input, because if I do, the game won't recognize my DualShocks, and I can't use DS4Windows because EA Javelin doesn't allow it.
