Xbox one controller wont sync to console no matter what I do

So, recently, I got back into Xbox again and wanted to play on the family one we have in our home. However, despite looking totally normal on the surface, it just does a slow flashing blinking light whenever I try turn it on and won't work. Since then, over the course of an entire day, I have tried practically every method suggested by youtube videos or reddit. If I plug the cord into it you need to connect it to the console, it works but only for about ten-fifteen seconds before doing nothing. I have done the method where you take out the batteries to drain the power and then try sync it again, nothing. I have hard reset the console and then try sync it again, nothing. I have done basically every variation or method that people claim to work wonders in the videos comment sections or reddit and received no results. There is no damage on the outside so I am still sure it is fine and must be some problem with syncing I haven't figured out yet which is why I have still kept trying. Is there still hope or should I just purchase a new controller and call it quits?
