1. Verify Integrity of Game Files

Open Steam and go to your Library.

Right-click on "Hand Simulator" and select Properties.

Navigate to the Installed Files tab (or Local Files in older versions).

Click Verify Integrity of Game Files.

Let Steam scan for missing or corrupted files and re-download them as necessary.


2. Update Graphics Drivers

Make sure your graphics drivers are updated:

For NVIDIA, use GeForce Experience or visit NVIDIA Drivers.

For AMD, use Radeon Software or visit AMD Drivers.

For Intel, visit Intel Driver Support.



3. Disable Overlays

Overlays like Steam's own, Discord, or others might interfere with the UI.

Open Steam, click Settings > In-Game > Uncheck Enable the Steam Overlay while in-game.

Disable overlays in other apps like Discord or GeForce Experience.


4. Reinstall the Game

If verifying files doesn’t work, uninstall and reinstall the game:

Right-click on "Hand Simulator" in your library and select Manage > Uninstall.

Reinstall it from Steam once the process is complete.



5. Run the Game in Compatibility Mode

Locate the game’s installation folder:

Right-click the game in Steam, go to Properties > Installed Files > Browse.


Find the game’s executable file (usually .exe), right-click it, and select Properties.

Go to the Compatibility tab and check Run this program in compatibility mode, selecting an older version of Windows (e.g., Windows 8 or 7).

Also, check Run as Administrator.


6. Check for Missing Fonts or Corrupted Files

Some games use custom fonts. If they are missing, reinstalling the game should fix it.

Ensure your system fonts are working correctly by testing other applications.
