Computer is Mac with Monterey 12.4 on it. Photoshop Elements 2022 most recent upgrade is stuck on a which screen with application updates in a text bubble near the top. In the middle of the screen is a white circle with spokes around the outside edge. Spokes highlight to give illusion of spinning circle. No other messages displayed. Have been on this screen for over 2 hours.
