Hi BirkoffHimura,
Thank you for all the information. We have a ticket in for this crash and will continue investigating the crash. You can find it here: Unreal Engine Issues and Bug Tracker (UE-40773)
We have several D3D ‘HUNG’ crashes with different callstacks and yours match the report I linked above. Feel free to track the ticket as we continue to investigate and review this issue. Keep in mind that we don’t have a time frame on when this will be addressed so don’t rely on a fix to be made quickly if it is crucial to development.
