Hey @Nari_Page
Could you try doing a fresh reinstall of the game files? We’ve had some reports of this issue in the past and most of the time it was caused by some game file acting up. If that doesn’t help, could you specify what error message you get so we can look into it in more detail?
Thanks 
Hey @Nari_Page
By fresh uninstall we mean deleting the game and any saved folder it might leave behind after uninstalling.
Once you reinstall it, could you try as the error suggests and check the integrity of your game files as well? (by right clicking the game in your Steam library > Properties > Local Files) We would also suggest running a cleaning program such as CCleaner Light to clean up any registry issues that could remain in your system that could affect your game files.
