Crash when removing track from crate: Stack Trace included!

Legacy Products Engine PRIME
1

Situation:

  • Machine: Apple macbook Pro 15" 2018
  • OS: MacOS Mojave 10.14.5
  • iTunes is open and playing (not the track causing the crash)
  • Engine Prime is open and not playing
  • Drag an album onto a crate in Engine Prime
  • Make sure that crate is selected in the left-side tree view.
  • In the Search filter above the tree view, enter characters for the track you want to move
  • The track now shows in the right-hand side of the screen.
  • Drag that track in another crate. This works fine.
  • Once moved, right-click the track in the originating i.e. the source crate and right-click it, then choose “remove from crate”
  • Engine Prime now crashes.
  • This happens a lot but not always.
