I'm on a Quest 2.
I've had this bug for a while now even in the patch before the current one.
On a fresh download and install of the app I can use it fine. Once I close/exit the app the next time I try to open the app it gets stuck on an infinite loading screen. It's just the spinning loader going on and on - even if I leave it there for like 20 minutes and come back it's still just stuck.
I've been "getting around" this by uninstalling and re-installing the app each time, because the app only seems to work at first launch on each download. I don't experience anything like this in any other app, and I don't think it's a network issue because I encounter the same infinite loading screen on multiple networks (different ISPs).
