I am having a problem with the screen sharing feature. When I go into a Discord meeting and try to share my screen, the menu to select a window keeps going into a beachball and since it takes over the whole system, it gets stuck in this screen sharing UI and I cannot get out of it. I cannot force quit the app by opening the force quit menu, I cannot control other windows to force quit the screen sharing like Activity Monitor or Terminal, even force quitting Discord doesn’t get rid of the frozen screen sharing menu. Is there any way to force quit this screen sharing window when it freezes, eg putting an icon in the dock for screen sharing so I can force quit it if it freezes, and is there any way to fix the screen sharing feature from freezing altogether, like fixing corrupt files?
