The reason this solution has a lot of methods because I don't know many crucial details like windows version or what Graphic card do you have etc...

I would assume you downloaded the windows version. 

those solutions are for almost any RPG game not just my game.

it's a common issue with RPG Maker games as it often tied to graphics initialization problems since MZ relies on WebGL and browser-like rendering via NW.js.

Here are some methods to fix it:

1-Run as Admin 

Right-click Game.exe > Run as administrator.

2-Installing Visual C++ Redist 2015-2022 (x64 or x86) from Microsoft.

This may solve the Graphics issue then open the game

Note:  Be sure to download Visual C++ from the official sites

3- Update Your Graphics Drivers (Most Common Fix)

The most frequent cause is an outdated or corrupted graphics driver.

Determine your graphics card: Find out if you have an NVIDIA, AMD, or Intel integrated graphics card.

Go to the manufacturer's website: Download the latest official driver directly from the NVIDIA, AMD, or Intel support site.

Note: Do not rely on Windows' built-in "Update Driver" tool, as it often misses the necessary updates.

Here is a solution to literally bypass any problem with any RPG game MZ or MV 

but it requires Visual studio code 

Here is step-by-step: Open & Run the Game Using Visual Studio Code (30 Seconds)

Open the game folder in Visual Studio Code 

1- Launch VS Code  

2-File → Open Folder… → select the folder where you extracted the game (the one that contains Game.exe, www folder, package.json, etc.)

3-In VS Code’s left sidebar, expand the www folder and double-click index.html (in MV or MZ you won't find www folder. just open the game file in VS and you find a file name Index)

(It will open in the editor.)

Right-click on index.html in the file tree (or on the tab) → “Open With Live Server”  If you see this option → click it → the game starts instantly in your browser, no graphics error.  

If you don’t see “Open With Live Server”, install the extension first (step 4).

4-(One-time only) Install Live Server extension  In VS Code, click the Extensions icon (or Ctrl+Shift+X)  

Search “Live Server” by Ritwick Dey  

Click Install (takes 5 seconds)

Now right-click index.html again → Open With Live Server

→ Your default browser opens and the game runs perfectly (full screen with F11 if you want).
