How can I troubleshoot why itunes is saying Item is not available in my region in itunes?

Hello, today, when I plugged in my iPhone 11 to iTunes for windows 11, i was initially unable to access the store, and kept getting an error message stating that an item was not available in my region. However, after restarting itunes, It still did this after purchasing a song. It does not appear that it is due to one of the songs that I am purchasing not being available. How might I troubleshoot this issue?
