S3rafim I own a Quest 1 so haven't tried to run with Air Link just Link with a cable. It worked best for me when I opened the COM3D2 icon, then I verified that VR was on, and I hit start. Next I made sure that the window of COM3D2 was up on the screen and clicked with the mouse to get past the warning and info screens. When I saw the menu and heard the music I then put on my headset.
After doing this a few times I was able to start from the recent app shortcut from my headset.
