Why does my game have a GDevelop icon?

My game installer has a Gdevelop icon. Also, the game itself after installation has an icon like that of Gdevelop. But there is an icon in the project itself in my game. This problem is on Windows. Why is that? This is possibly a bug. How to fix it?

I am having this problem too. On macOS (Big Sur), the icon works fine, but when I tested it on windows, it was the GDevelop icon. If you find the answer, please tell me!
