Interactive is not involved. Just regular render window.
I render from the perspective window, let it run for a bit then cancel, then move around in the viewport and render again. Then cancel after a few passes. Then on this third or sometimes second render it crashes upon hitting the render button.
I have also noticed crashes while getting materials eg - from the material editor, get material, scroll down to corona material, it seems like as it is rendering the small previews it crashes.
I have also experienced interactive crashes but I tried with and without interactive started and I get the same crash.
Hope that helps!
Best,
Matt
