While on the 6.12betas Logos would "randomly" crash from me. It was usually an instant crash with no hanging or error reporting, just an instantly off situation. As far as I recall, the only thing I was ever doing at the time, was scrolling in one of my Bibles (I've consistently been on one particular layout in the last few weeks...). Since there were no error reports and since I couldn't narrow down what panel/resource/feature was causing the crash I simply lived with it.
Since I'm on 6.13 I've had another crash, but this time it produced an error report and crash log, so I'm attaching the logs.
