The last file that MC saw, right before it crashed, was this one:
/Users/HW/Library/Mobile Documents/com~apple~CloudDocs/Downloads/Music/Hummel_ Bassoon Concerto Clarinet Quartet/Tk06 Johann Nepomuk Hummel Clarinet Quartet in E flat major WoO 5 S78 I Allegro moderato.m4a
I believe it was trying to do "analyze audio" on that file. It's fairly common for MC to crash if it finds a corrupted audio file and tries to analyze it.
You could try moving that file to another directory, where MC can not see it, and see what happens.
But I also notice that folder has a funny name "Mobile Data" and has unusual path names which imply that maybe it's not exactly a local file. Like maybe it's a replica of a file "in the cloud" or something. If it just wasn't fully available or something, that might have done it.
Generally speaking, I think it's a bad idea to import files into MC that are "in the cloud". There's no rule against it or anything. This is just my personal opinion.
Good luck.
Brian.
