Controller randomly loses tracking and feedback

One of my Vive Pro controllers randomly loses tracking while playing games like Beat Saber. Sometimes it is hard to complete a song because one saber will either fly away or disappear. Sometimes when it comes back on track it no longer provides haptic feedback when striking notes. I have attempted to follow a repair video I found online, but that only seemed to help for a short time. Do you have any advice on how to better repair my controller? Thank you.
