Strange bug when attempting to join live events in Horizon Worlds

I have a Quest 3 (about 8 weeks old). When I am using Horizon Worlds and try to enter any portal to a live event, instead of teleporting me to the event, the Quest Universal UI appears, showing a window for the Meta Store, specifically showing a page to install Horizon Worlds. But the strangest thing is that this is not the official Horizon Worlds store page - the official page has over 15,000 user ratings (with an average rating of 3.5), but the page that appears only has 16 ratings (with an average rating of 2.3)! Also strange is that it has a "download" button, while on the official store page it has a "start" button (because, of course, Worlds is already installed on my Quest 3 as part of the Universal UI and it cannot be uninstalled or re-installed). Also, when I clicked "Install", it said "Installing" but the progress bar got stuck at nearly 100% and nothing happened.

You can see in the screenshot here, I tried to join the "Hot Ones" live event from Horizon Central, but when I clicked "Join" the store page (seen on the right of the screenshot) opened up. If you look closely, you can see in the bottom-left of that window that that version of the app only has 16 ratings with a score of 2.3, and also that the "Download" button is enabled!

The "bogus" Worlds store page that opens when I try to join a live event in Worlds.

The next screenshot shows the official Worlds app from the Meta Store. You can see that this one has 15K ratings with a score of 3.5, and only a "Start" button, which proves that these two store pages are not the same version of Worlds!
