starter asset to package manager is broken

Starter Assets - ThirdPerson | Updates in new CharacterController package
Even if i download and run the starter asset of the above, it does not appear in the package manager. The other asset is added to the package manager well, but this starter asset says it's purchased but it doesn't appear in the package manager even if you press Open in Unity

I tried logging out and going back in or turning off the computer and turning it back on, but it didn't work
