Vive Cosmos controller trigger button problems

[RafSai]

For a year of using the set (+- 600 hours) there were problems with the trigger on the right controller.
The trigger just stops seeing the click, even though I'm holding it down at this point.
Or it makes 3-4 clicks in one press. I didn't drop or hit the controller. Played carefully. Idk what to do.

And it stopped making a vibration at the half-press, meanwhile, everything is fine on the left controller.
