R2 trigger is always fully activated

Hello, I have a problem with my DS4 v2 where the R2 is always fully pressed even when I dont touch it or any other button is being pressed. In a PS4 this leads to no button on the OS doing nothing until I hard restart the controler. In racing games the throttle ends up being always pushed to full. I replace the silicon part and cleaned the contacts behind the trigger and the issue persists. The R1 buttons works fine.

Thank you if you can help.
