After deleting it, do I need to update the certificates and republish the app? I first removed the group in the application and released a new version, but it still didn't work. After seeing your reply, I tried deleting the Group in Identifiers on the developer website, but that also didn’t work. Could you explain the steps in detail?

I am still encountering the issue I previously described. Interestingly, when I create a new visionOS app from scratch, it runs without any problems. However, the issue persists when I attempt to run my two older projects. I am at a loss as to how to resolve this and am seeking your guidance and assistance.
