Raiju Ultimate: PC can't detect Bluetooth connection

As the title says, my Raiju won't connect to my PC via bluetooth. I had it working fine ago probably a year and half ago, but put it away during a move. Wired, Wireless, Xinput, it all worked flawlessly. Fast forward to yesterday. I tried to turn it on and it wouldn't connect. No big deal I thought, Ill just repair it. However, when I put it into pair mode (PC BT, hold in the power and options button) it starts to blink, but Windows won't detect it. I tested my connecting an Xbox controller with bluetooth, and my pc can detect that, so I don't think that is the problem. I tried pairing it with a different computer and it was detected right away, so I'm thinking it has something to do with corrupt drivers or something, but I'm not too sure. Any help would be greatly appreciated.
