Big Sur Update causes Apple TV App (iTunes) to freeze

Since the last couple of Big Sur updates, Apple Tv application (iTunes), doesn’t respond (freezes). My Drobo 5D appears on the Desktop and I can access files, using either Thunderbolt or USB. However, whenever I try opening Apple Tv app or the Music app, they freeze. If I attach my old Drobo S using USB, instead of my 5D, the Apple TV application works. Does anyone else have this problem and do you know if Drobo next firmware update will address this issue?
