Stuck in "Loading Structures"

Hello all.
While trying to launch my save game yesterday after getting the game, it got stuck at loading structures. I waited around 30 minutes for it to load but it didn’t. So far I have tried, waiting, submitting a bug report, sending an email to hello@airportceo.com, and reinstalling the game. I’ll include both the output log and the problem log.
