Jurassic World Evolution 3, released in 2025, is a popular simulation game for which players have reported startup issues. This is what one JWE 3 player said on Steam’s forum: “The game [Jurassic World Evolution 3] has completely and entirely stopped starting up… This started when it crashed due to the driver’s glitching while I was in the bathroom, and ever since it hasn’t started up at all.” This is how you can fix Jurassic World Evolution 3 not launching on Windows PCs.
Verify the Jurassic World Evolution 3 Game Files
First, start your troubleshooting by verifying the Jurassic World Evolution 3 game files, which have worked for some players. Steam has an option you can select to run a verification scan for any specific game.

Set a DX11 or DX12 Launch Option for the Game
Another player-confirmed way to fix Jurassic World Evolution 3 not launching is to set a DirectX 11 launch option for the game. Or you can set a DirectX 12 launch parameter for JWE 3 if DX11 doesn’t work. These are the steps for setting DX11 or DX12 launch options:
- Start your Steam gaming client and open the Library within that software.
- Next, right-click Jurassic World Evolution 3 in the sidebar to select Properties.
- Enter -dx11 into the launch parameter box.
- Try starting Jurassic World Evolution 3 with the DirectX 11 launch parameter set.

Unplug Superfluous Peripheral Devices
Third-party peripherals, such as gamepads and joysticks, can sometimes generate startup conflicts for games. To address that potential cause, unplug all unneeded peripheral devices from your PC, except the keyboard and mouse. Then, try starting the Jurassic World Evolution 3 game.
Rename the Config_Local Folder
The Config_Local folder for Jurassic World Evolution 3 stores configuration files. Renaming the Config_Local folder is a potential way to fix Jurassic World Evolution 3 not launching because that resets configuration files to default settings. This is how you can rename the Config_Local folder on a Windows PC:
- First, go to the Users > [user folder] > AppData > Local > Frontier Developments > Jurassic World Evolution 3 directory location in File Explorer.
- Right-click the Config_Local folder to select Rename.
- Input Config_Local.old for the new folder name and press Return.
