1. Repair Microsoft XNA

2. Install Visual C++ dependencies

Like XNA, Visual C++ dependencies are necessary for apps and games to launch and run Windows. These dependencies are usually installed with the game or Steam, but if the installation was skipped (for whatever reason), you must download them from the Microsoft website and install them manually.

1. Open the official page for the Visual C++ Redist Packages download.
2. Click on the Link and download vc_redist, which suits your operating system architecture.
   ➡ X86 is for 32-bit systems.
   ➡ X64 is for 64-bit systems.
   
3. Run the installation package and follow the steps.
4. Restart your PC

3. Delete Steam cache files

Steam cache files are known to cause various shader issues. You should head to the Steam directory, back up the appcache folder, and delete it. If anything goes downhill, you can always return the backup to its original location.

1. Use the Windows key + E shortcut to open File Explorer.
2. Navigate to the default Steam directory by pasting the following path C:\Program Files (x86)\Steam. If you changed the Steam installation directory, navigate to it.
   
3. Right-click on the appcache folder and select Copy.
4. Use the Windows key + D shortcut to go to Desktop and CTRL + V shortcut to create a backup of the appcache folder.
5. Return to the Steam directory, right-click on the appcache folder, and select Delete.
   
6. Restart your PC and run Terraria through Steam.
