Never had a previous issue launching the game on my PC, but this evening it crashed twice in a row while loading the game. I launched the game from steam, and otherwise did not interact with the game before the crash occured. Both instances were at 15%, at the Building Prototypes stage. Unsure what could have occured with my system since I last played a week ago to cause this consistent crash. Attached are the crash logs from my 2 attempts to launch the game.

Have you verified the game files through steams verify option? It's crashing on something that runs every time you start the game (something that runs every time every player starts the game).
