Hi Jiella,
There have many conditions is able to trigger the event 1002 occur, the current information is difficult to determine the exact reason, in most troubleshooting case we can first
try to clean up the disk or reinstall the application then monitor the issue again, but if you want to perform the further research that issue need a memory dump analysis and I would like to suggest that you contact Microsoft Customer Service and Support (CSS)
