Meta Quest 3 not connecting using Air Link

I’m just setting a new Meta Quest 3 headset and I cannot connect to my computer using the Air Link feature. Is it possble that this could be something that Avast Security is blocking? Is there a setting or rule that I can change/create to get wireless communication between my computer and headset working? I follow all the guides exactly, but it just hangs at the last step when I press the pair button. I’ve installed, re-installed, etc, I’m getting the same result. Any insight would be hugely appreciated!
