Hi jiahaokoh,
Thanks for submitting this data through the crash reporter. I was able to link this to a bug that has already been reported, UE-35509. Any additional information that you can provide to help us reproduce the issue on our end will greatly decrease the time it takes to resolve this issue…
Please provide as much information as possible such as: Are you able to open a previous version of the engine? If so, does it function normallly?
Thanks,
