I formatted my Mac Catalina beta, because I expected the redesigned Music app to successfully import iTunes Library.itl file from Time Machine Backup.

However, when I import > select the file, nothing happens and even if I manually add ~/Library/Music/iTunes/iTunes\ Media/Music file into Music app, some of the music files are missing.

Is there any way to completely reset Music app's preferences, thereby re-initiating iTunes Library import sequence from OS update? Or, is there a way to properly import previous iTunes Library from Music app?

Take a look at ~/Music/Previous iTunes Libraries/. There are old copies of your .itl file stored there.
