There is only a single crash dump can be seen on the diagnostic report so it is not possible to find a pattern in the crashes. If you are using CCleaner or Windows disk cleanup, stop using them as they will delete the dumps to save disk space.
It looks like Sophos Antivirus might playing a role in the crashes.
