Seems like a reproduction might be possible, see new dmesg output with striking similarities:

Space Haven (a steam game) crashed, which somehow seems to have snowballed into the client (possibly through the overlay or something). This is speculation based purely on the observation that the two crashes seemed to have occurred in the same moment. A key insight is that the steam crash did not cause the game crash, as I was performing a reliable bug reproduction[^1]. A new core dump is attached.
[^1]: The game crash can be reproduced by loading the attached save game, selecting the combat robot station and moving it somewhere else on Beta 2 - Build 7. Once the object has been deconstructed, the game will crash.
Nothing extracted yet.

Please describe your issue in as much detail as possible:
The steam client sometimes spontaneously crashes. It's rare, but I've kept my eye out for it and finally caught one. Unfortunately I reported it via the Steam Client two days ago so I have already forgotten most of the details (I forgot about this repo -- my bad!).
