Why is UE4 crashing upon rendering pictures?

Hi people,

I have built a nature level and deployed different cameras. Those cameras have keyframes for position as well as focus distance. Every single time I try exporting the movie sequence as .JPG or .PNG, UE4.16 as well as UE4.15 crashes at random places. Exporting a video however is fine for the most part, although I’ve seen it crash every now and then.

This is what the dump file is telling me:

No feelings on this? I’ve tried it on few different machines and the rendering crashes every time, albeit randomly.
