grateful if there's a workaround or explanation. Can ignore and reload but a nuisance when it happens
Looking at your crash log it doesn't look like one I've seen before, and I can't tell exactly what happened just by looking at it. It may be specific to the type of hardware saved with your project. Are you able to provide a copy of one of your projects that reproduces this crash (or at least the "Channel Specification.flxio" file for it)?
