Apps like iHeartRadio and YouTube Music Disappeared when Updating to watchOS 26

When I installed watchOS 26 onto my Series 10, iHeartRadio was the first app to disappear immediately. Then the next day (today), YouTube Music was gone from where it had been. I then checked again a few hours later and there was another app gone (I still haven't been able to figure out which one it is, however). When I went to the App Store to see if they had just deleted themselves somehow or if they needed updating, they just showed the "Open" button as if they were still there, but when clicking on it, nothing happens. I really don't know what to do about it, because I've kind of tried to do everything I could, and nothing's happened to change it at all.
