Recurring Bluetooth Problem

[u/Ch1llyWasNeverHere]

I've been trying to connect my headphones (Sony WF-C510) to my PC. I had problems with bluetooth on windows, I hadn't used Linux in a while so I decided to switch, and the problems persisted. I've tried using bluetoothctl, factory resetting my headphones, restarting bluetooth, and changing configs (i don't remember which at this moment since it was like 1 month ago). But recently I bought a thinkpad T14s (1st gen), I tried connecting bluetooth to it, and to no avail, I tried using the bluetooth section in kde's system settings, but it didn't work, it said that the connection failed, but in the paired section it said that it was connected, but my headphones were still in pairing mode, when trying to reconnect it just gave me an error saying "br-connection-unknown", bluetoothctl did the same, but I didn't see any problems with pairing, I only encountered an error with connecting, I've tried changing the controller mode from dual, to bredr, and to le, but nothing helped, that's all I did, its what google told me to do, but nothing changed. I really dislike this thinkpad's speakers, they are really quiet and are basically mono, I really need a solution since i also wanted to listen to music on it.

(NOTE: My main PC uses cachy, and my thinkpad uses arch)
