Step 1. Close Palworld and Steam. Press Windows + R, enter %localappdata%\Pal\Saved, and press Enter.

Open the Palworld Saved folder through Windows Run

Step 2. Back up the folder, then rename Config to Config_Backup.

Download Microsoft Visual C++ Redistributable packages for Palworld

Step 2. Restart your PC after the installation.

Step 3. Launch Palworld again to check whether the startup issue is resolved.

Step 2. Uninstall Palworld through Steam, open the previous installation directory, and delete any remaining Palworld files.

Step 3. Restart your PC, reinstall Palworld on an SSD with enough free space, and launch the game before restoring saves, mods, or custom files.
