Apple Wallet Has Stopped Working

A few days ago, when I opened Apple Wallet, I got a message saying it was not working. All of the cards listed also said they were not working as well. This isn't a payment issue--the wallet itself is not working. After rebooting my phone several times and deleting and re-downloading the app several times, I finally got someone from their tech support who suggested that the Public Beta 17.2 update was the issue, and she suggested I wipe my phone and re-download the earliest iCloud back up I had. Well, I did this, and unfortunately my 15 Pro Max is new, and the download was from my 13 Pro Max, which included the Public Beta 17.2 update. So, Apple Wallet is still not working and I cannot use Apple Pay.

Is anybody else having this issue? It is so frustrating, because if the 17.2 update is the issue, I can't get it off my phone. And when I called support again, the agent literally put me on hold and never returned. I have looked at all the ways to remove an update, but none have worked.
