Yep, Ok so it is an open world scene and I load the persistent level. It has a few technical things like lights etc in it. I right click in the viewport without dragging it, waiting for the context menu, instead the crash happens. When I click on the Snap icon to turn snapping off, no crash happens. When I right click and drag the viewport around, no crash either. I removed all items from the persistent level with the same result.
It does not seem to happen in the simple startup world that is loaded on editor startup. What it has to do with the loaded world, i can not say, but it is clear that the cause for the crash is RMB down-up without moving the mouse.
EDIT: You have to be in TOP view mode for this, perspective will not crash
EDIT: I had another crash. Was dragging a bunch of objects with snap sockets around, then left clicked outside of the selected objects in the viewport. A dot appeared and crash. Before the crash, the snap did not work either although it was turned on, the dragged objects (I was trying to extend a city wall by copying segments) would not snap to the existing ones
