How to find a problem with song that crashes iRealPro?

Using Apple Mac OS Catalina 10.15.4 on a 27" with 24GB RAM and no ther apparent problems with OS or other applications.

Specifically - tried to play “Can’t help falling in love”, composer Elvis Presley (Peretti-Creatore-Weiss) from the pop 400 songs imported to iRealPro from the forum. Opens but immediate crash when play clicked.
No other report other than the OS report for Apple.

Happens on this song every time! Must be a way to find the problem as it all looks ok on the screen!

Has anyone else had this, is there a way to find the problem with this song as all others that I've opened seem to play OK.

Thanks
