A spot is no longer tactile

Hello I don't know exactly when but when I buy the Fenix 7 pro, first it was ok. But some weeks ago appeared a problem.

There is a spot of the screen that is no longer tactile.

For example :

-when I launch the wheel menu, I can't select the item in that spot. It will launch the right or left item. 

-If I launch the Garmin pay, when it ask for the pin code, I can use the 2 because it will write 1. ( If I hit 1 it will write 1)

-on the home screen I can't launch the FC graph ( by holding the FC number)

Is there a hidden menu to test the touch screen?

I'm on v 8.37
