Controllers no longer work after a week without use

I recently bought a used Meta Quest 3s, it had no problems whatsoever, it was actually working perfectly! The original owner had used it for just a few months. (I did check everything, it was in perfect condition)

Anyway, i used it for a few weeks, played a few games, once again (i cannot state this enough) it was working perfectly.
One day, after playing with it, i charged it and let it rest on my shelf for a week

Yesterday i thought "Oh well, i wan't to play some VR Games", so i put it on, it updated and suddenly it wasn't detecting my controllers anymore. They wouldn't turn on when i grabbed them and the meta app said they were disconnected.
I changed the batteries, nothing worked.
I cleaned the battery ports, nothing changed.
I un-paired them (with the meta app) and now they couldn't 100% pair. The LEDs would flicker, but wouldn't vibrate (even after a billion seconds) nor finish connecting. (It would even display a little UI on my vr saying the controller was updating, but after that, radio silence) And if i left the pairing screen, it would display that my controller was paired, but again, wouldn't work.

Problem is, after i did that, the left controller STOPPED working. LEDs wouldn't show up anymore and it wouldn't pair at all. I've done everything i've seen online (cleaning, changing batteries etc) but it just doesn't work anymore.

As a last resort, i decided to factory reset my VR. How do you guys think it turned out?
Anyways, here i am.. Stuck in the pairing screen because my controllers just don't want to work anymore.

TLTR: VR was working. I stopped using it for a week. It updated. Now left controller died and right controller doesn't want to pair properly (and doesn't work) + i'm stuck in the pairing section
