Brief description of the issue: App loads correctley and loads saved tracks and playlists, but without any artwork, every playlist is empty and music playback doesn't work. The web player works without any issue in Chrome browser.
The issue appeared I belive after installing Windows using Bootcamp Assistant and might be caused by deleting some files before the install to free up some disk space.
Steps to reproduce the issue:
What steps you’ve tried already:
