I was having the same issue in Archlinux but after Episode 1 end-screen instead. Running from the terminal I saw that the stacktrace started like so:
Stacktrace:

Since the crash was in a Joystick function, I unplugged the driving wheel I had connected to the PC (the wheel wasn't even turned on by the way) and after that it didn't crash anymore. So you might want to try disconnecting any joystick you have plugged in.
