Popup 'Allow connected device to access files' appears on opening palm when no device is connected

I am new to Unity and developing for the Meta Quest 2. I created a simple MR scene with pass-through enabled and an interactable object but encountered 2 issues.

1: Passthrough only works in my app for a stationary boundary, when I switch to room-scale boundary I get a black background.

2: Every time I open my palm a pop-up stating 'allow connected devices to access files' appears for a few seconds. It cannot be interacted with and disappears on its own after a few seconds. My Quest is not connected to anything, and it is offline.

Does anyone have any idea how to get around these?
