What would cause a bumper button to not work

I have a PS5 Dualsense remote with a suddenly non-functioning R1 button.

  • No physical damage to the remote from dropping/excessive force has been exerted
  • No water damage
  • The black plastic part of the button is in the correct position. Removing to access the silicone part of the bumper button and pressing with a pry tool/screw driver does not work
  • R2, L1 and L2, as well as all other functionality is perfect
  • The remote is a v1 remote

I've tried disassembling the remote and investigating, nothing out of the ordinary to report and I'm at wits end. Any guidance would be appreciated.

Ended up being a microtear in the ribbon cable through some of the middle connections, which obviously affects the R1 button in particular.

Easy enough to replace, but I can imagine that with the design of the right ribbon cable being more exposed it could potentially lead to more issues over the left one

Replacement ribbon cables can be found on Amazon. Watch for the generation controller you have though as apparently there are several and some use slightly different cables.
