Big Sur? Unable to remove audio tracks from playlist

I use ManyCam to teach virtual high school. I use the playlist feature to add a “Song of the Day.” I have recently upgraded to Big Sur (should have waited). Since the upgrade, when I try and remove an audio track from the playlist, the app crashes. Please update to resolve this issue, or please let me know if there is something I can do from my end. Thank you.

@ieo Can you please investigate this issue?

We were able to reproduce the issue, will be fixed soon.
