DS4 Controller not responding correctly

I have the exact same issue. For me it presents as such:

The game thinks I am using mouse and keyboard while I'm using a controller. So the in-game prompts change from X/Y/A/B to "enter" or different symbols/prompts. The controller input for entering into the menu translates to a backwards dash. When I press "B" to go back in the menu it trips up/flips out. It wants to translate multiple inputs at the same time. The audio signals as much, giving me at least 3, maybe 4 or more "clicks".

Here's what I tried:

• Unplugging keyboard and mouse and other peripherals, just to check if these were causing it. No solution, the issue persists.
• Different controllers, checking if the controller is faulty. No solution, the issue persists.
• Tried the same controller on different games. No issue. So this proves it is not the controller.
• Checking file integrity through the Steam app. No solution, the issue persists.
• Uninstalling the game and reinstalling through Steam. No solution, the issue persists.
• Checking for Windows updates and GPU updates. No solution, the issue persists.
• Raising a Help-desk ticket with EA. No solution, "we do not support your peripherals".

I really want to undo the latest patch, but EA support is no help. The game has become unplayable.
