@BigBalli Thanks, BigBalli. It's not about the product identifier because an old Mac App Store application that has been available also fails in the same manner. Also, it's not about the configuration, because, I created a new one, but an old Mac App Store application still manages to fail in the same manner. The current situation is a total mess. I guess I should not have installed Xcode 26. Now, I cannot even sign in and out of an iCloud account so easily. The System keeps running a progress wheel for an hour. I'm bending towards buying a new Mac mini. I'm waiting for a new model with M5.
