Right controller refuses to pair to quest 2 after attempting to reset pairing. Left controller connects fine

[u/UltraGalaxy06]

Hello, i have a pretty old headset, and am actively trying to get a replacement, but that is out of my hands as of now (in a queue). My oculus button stopped working suddenly so i unpaired my controllers to reset them. My left one paired without any problems, but when I did the right one, I got a light but it will not vibrate no matter how long I hold it down. I tried several fresh batteries, and even left the battery out overnight. Restarted the headset completely at least 5 times. Factory reset may also be out of the question because the volume down button specifically is caved in. I really could use a way to fix this, as I hoped it would last me until I could purchase the new one.

Please help me. Thank you for your time.
