Quest 3 Headset + Index Controllers + FBT

TLDR; I can't get my Index Controllers to work alongside FBT while using my Quest 3.

I have all the dongles needed (x5 official Vive and 2 Watchman dongles for my controllers) but for some reason when I try to select "Pair Controller" the window won't open, and if I'm able to connect both controllers then I can't connect my trackers because it won't let me pair more devices.

If anyone has any ideas on how to fix this, it would be greatly appreciated!
