Logic Pro iPad Session Players Studio Piano doesn't install

After installing Logic Pro on my brand new (one week old) iPad Pro (11" 4th gen / M2 - 512GB) with iOS 18.4.1 , I wanted to install the session player soundbanks. All banks except the "Studio Pianos" will load and install. "Studio Pianos" load all 3.52GB but doesn't install the content on my iPad. I tried it several times, with the iPad connected to my power adapter. Even re-installed the app and all the content once again - does not work. It is quite annoying as I spent much $$$ to have a pocket pro solution and now it doesn't work as it should. Please help
