I just got this "non-recoverable error" as well - https://i.imgur.com/fobb6cy.jpg

I was deconstructing a number of belts with with iron plates on them, and didn't have room in my inventory for all of them, so queued some hand-crafting to use some of the plates I had. Then, I used the deconstruction planner to to remove some more belts with iron plates on them and the drones started doing them, then I hit the crash.

Same error here. Easily recreated too.
I have the savegame just before it happens and can repeat the same actions
