Can't click button or select text on desktop only

hey guys. I cannot click a button (with a trigger to a popup) or select text on desktop. I’ve already set the Z-index correctly, but it still won’t on desktop - only on mobile - which is strange. the cursor doesn’t even have a pointer when hovering on the button.

do you have any idea where this is coming from?
