It happened while playing the game. I wasn't doing anything in particular, I assume the bug is triggered by items actively moving on belts without involving any player interactions.
2. What happened?
Game crashed
3. What did you expect to happen instead? It might be obvious to you, but do it anyway!
The game runs without crashing

4. Does it happen always, once, or sometimes?
It happens occasionally, more often when things are happening in the world (science production, space platforms moving, etc.)
