Thanks for sending over the logs.
I've just uploaded a patch which fixes a crash that some people were experiencing on their second startup if they had enabled the fullscreen setting in their first session. I'm not sure if this would fix your issue too, but I hope it does. I'd appreciate if you could let me know, and sorry for the inconvenience.
Hm. You could try "disabling the Nvidia driver" as described in this thread (I'm not sure exactly what this means, but it seemed to work for at 2 people): https://steamcommunity.com/app/1923790/discussions/0/3395163747096165276/
(also, just for the record, the two ERROR lines about the Steam API are expected, they happen even when running the game normally.)
Great! :)
For any future readers: This other Steam thread recommends not disabling Nvidia drivers, and instead:
in the Nvidia Control panel under manage 3D settings set Anisotropic filtering, Anti-aliasing, and Preferred Refresh-rate to Application Controlled.
