Apple TV app on my iMac collapses post macOS Sequoia update

Hi there, before with Catalina I have all my movies, tv shows, personal videos (Thousands) and so on stored into TV.app without any problem: doing this I can watch my contains on each Apple TV I have at home on different televisions...

Unfortunately once updated to the new Sequoia the app remain open only if I browse movies or personal videos but when I click on TV Shows it collapse every time, also in this situation also the multimedia sharing switch off even if it is authorised with my In Home coordinates...

Have you any idea how to solve this?

Thanks a lot...
