I'm sorry to hear that. I made this game with Godot 4, the newest version of Godot Engine which only supports Vulkan graphics, not OpenGL. Since I don't have info about your graphic card, it is said that "You can try updating your graphics card driver to the latest version. If you are using an NVIDIA graphics card, you can download the latest Vulkan 1.3 general release drivers. If you are using an AMD graphics card, you can find information on the added Vulkan support for AMD Graphics Products." For me, I will try to find a way to convert the game back to Godot 3.5 the older version that is friendlier for most graphic cards.
