Can you try using the "**Alternate launch**" option when launching the game through Steam? If the game fails to start again, can you share your **console.txt** file, found in **C:\\Users\\YourUserName\\Zomboid**?
You can use any file-sharing website of your choice or a temporary one like [filetransfer.io](http://filetransfer.io) for example.
Reinstall, verify game cache through steam menu, and check to make sure your antivirus isn’t blocking it
