Hi kyaRicsi. I just faced this problem this week and this is what I did to solve my problem.
I went into the Documents folder of Fifa 20 and deleted the buttondata configuration file. I did reinstall the game, but you can try it without reinstalling to see if it works.
After deleting the buttondata configuration file, I selected my logitech controller to work in X instead of D. Then I went into the device manager, and found out that the controller is not recognized. So I clicked on update driver, and then selected to search my computer for update files instead of online updates. Once you select that, you will see a list of drivers for lots of different things. Scrool down to the bottom, and select xbox peripherals and then select the xbox controller (the first option). Once the driver is assigned, you can go in your game and it works. Let me know if it worked
