Trying to do airlink and it pairs but not launchable.

Airlink used to work but now it just a launch button with it being grey.

I've tried:

Factory resetting my VR headset

Repairing the meta quest pc app

updating all pc required drivers and updating to latest update on both devices

Most results just say 'Enable the airlink button on the meta quest pc app' but its not there!

what am I doing wrong?? its been doing this for months and support isn't helping either and giving me complex stuff. I've searched up what to do but its too much and I don't trust any of it.
