iCloud is unavailable

iCloud looks unavailable in my iPhone 13. Cannot see the iCloud storage usage, or any other option in the menu, and Private Relay looks “unavailable”

Also, I cannot access to any file in the cloud in iCloud Drive, and the loading spinner keeps there for ever.

p.s. I tried to contact to support but it redirects always to the iCloud Support Home Screen.

p.s 2. I didn’t find any issue in the Apple Status of Services page.
