Anytime I’m working on an arrangement it seems likely to crash. Most often crashes occur after hitting the play button, making any kind of length adjustment to a section of a track, when exporting to a sound file, and slightly more rarely just doing anything within an arrangement.
This can occur even in arrangements that utilize zero plugins and are just audio recordings without effects or any MIDI instrumentation, etc.
I hopped into the program real quick and made a crash occur, then took a snippet of what the debugger says. You can find it here though I doubt it will be very helpful because it seems like I am missing something to debug it properly:
