I have around 5 hours of play time and was close to finishing the introduction, when I decided to start a new map. When going to the main menu, the game crashed and I haven’t been able to start it since. Whenever I try to start the game through Steam, a little window with a yellow airplane and a big red exclamation mark in the corner pops up and disappears again after a second - that’s it.
I have tried to reboot my PC, reinstall the game, delete local saves and disable Steam Cloud saves, none of which have solved the problem.
I have also read in other threads that there’s an output.txt file somewhere, but I cannot find it anywhere in the game files or the AppData directory.
That box with the plane icon comes from the Unity engine.
I do get sometimes crashes too when I want to leave any savegame back to the main menu, but after that it is still possible to start the game again.
