a pop-up appears when switch to parallel(windows) from Mac

Hi,

I am currently using the parallel desktop 17, mac os 10.15.7

Everytime when I try to switch parallel (office) in coherence mode from Mac apps, a pop up would appear, then it would disappear after 1 second

I have uploaded the photo for better description, does anyone know the reason? it is so annoying...
