ditto, experiencing the very same, but on Win7 Ult. doesn't seem to matter if I'm running recipes, hand folding, or just watching it sit there...and crashes are coming more frequently now.

Four crashes this morning in less than an hour -1278.

Crash on Windows 10 Pro.

My laptop is one that would crash every few minutes because of an audio issue. An audio release was issued on 7-25 and since then I have had zero crashes which is exceptional. With the latest update though my laptop has now crashed.

Attached log.txt file.

Thanks folks, I've let the team know the crashes are happening. Thank you all for the logs - those really help us the most.

I have been able to crash 1278 3 out of 3 tries by running DRW on it - twice during shake and once during wiggle. I have not been able to come up with a short deterministic script that crashes it, though I may not have tried long enough. 3 logs attached, no error message in any. Only one client writing to the log at the time.

Just for grins I tried the current release on the scorpion toxin puzzle from June (1244), with disulfides. There were no puzzle comments or feedbacks on that puzzle, so I assume it ran fine in June. Now it crashes reliably within a half hour. Logs attached - crashed once during wiggle immediately after IRC server disconnect, once during wiggle with unhandled exceptions reported in log.txt, and twice during wiggle with no exception reported.
