Hi Jonathan,
Thanks for your reply. Unfortunately these crashes don't seem to be creating dump files, I've checked the Minidumps folder and there isn't a corresponding file for the crashes. I've discovered that the problem happens when I try to freeze ANY aux track, regardless of the plugins attached. It doesn't happen for normal tracks, which freeze just fine. I feel like there should be an obvious reason for this, or something I'm just not understanding?
Thanks for your help.
