Can that be reliably replicated?
On my computer, yes. I didn't have a second one to test. As far as I could test, the crash only happens with the OST of Shin Megami Tensei: Nocturne, which you can get from Zophar's Domain (
Link). Other Atlus OSTs might be affected, too,
but I didn't test them, yet. Digital Devil Saga crashes as well, but immediately on starting a song. And with a segfault, instead. The Persona games use CRI ADX, so they're unaffected.
Specs:
macOS 10.15.4 on a Late 2012 iMac
AO is v2.2.1, as you can see in the crash log.
Steps to reproduce:
1. Download the SMT:Nocturne OST.
2. Drag the downloaded zip file into AO.
3. Play any song.
4. Either wait for it to finish playing or change to another song.
Expected result:
AO should change to the new song
Actual result:
AO will crash (see log above)
