Zoom disappears when screenshare starts and stops

Every time we start or stop a screen share, we have a member who's Zoom disappears and takes her to the computer home screen on her laptop. She has to click on the Zoom icon again to get back to the meeting. this is a fairly new problem that she has encountered. Steps she has tried without success: updating Zoom, Uninstalling & Reinstalling Zoom, trying different browsers including Chrome & Edge.
