Game crashes on start-up
Some players are reporting issues with the newest updates to Project Zomboid, where the game crashes on start-up before even reaching the title screen. This appears to be affecting users on both Windows 10 and 7. Users have tried updating their drivers, uninstalling and reinstalling the game, and scrubbing the game completely from their computer, but have been unable to get the game to work. Some users have even allocated 6 GB of RAM to the game, but it still isn’t working.
Workarounds to get the game to start
There seems to be no clear reason why this is happening, but a workaround is to start the game through the .bat file in the installation folder. To do this, right-click on the game in your library, click “Properties”, go to the “Local Files” tab, and then click “Browse local files”. From there, you can launch the game using the .bat file.
Another workaround is to disable all mods, As well as verify game files on Steam. You can also try updating your GPU driver or the Visual C++. If you have two Steam directories, make sure Steam recognizes both. You can also try running the 32 bit .exe instead of the 64 bit. More extreme measures include deleting the Users<YourUser>\Zomboid folder or completely uninstalling and reinstalling the game.
Yet another is to turn on 3D corpses and 3D models in the options menu. Finally, gamers with Intel HD Graphics can try allocating 6 GB
Uninstall recent Windows updates
Some users are reporting issues with getting the game to start after a Windows 10 upgrade patch.
In order to uninstall recent Windows updates, you must first go to the Start menu and search for Settings. Once you have located the Settings option, select it and then navigate to Update & Security. Within the Update & Security option, there will be a View Update History option – select this.
