It seems to me like there are issues with the GPU.
Please follow these steps:
Verify the game as written by [MCG] RedWolf [CZ] ~.
Before performing these activities, attempt to enable the game using OpenGL or DirectX 11.
If this solution does not resolve the issue, please consider updating your GPU drivers.
If the problem still occurs follow these steps:
Download the Furmark* program link: https://geeks3d.com/furmark/downloads/
Run this program and perform a donut test for max 10minutes
If there are artifacts [black, purple, RGB squares, distorted textures, BDOS, black screen or the computer shuts down], it indicates a broken GPU
* To test your graphics card, use Furmark as a stress test. However, please note that this program puts a heavy load on the GPU, so use it at your own risk. It is important to promptly react to any issues to prevent damage to the graphics card.
Alternatively, you can test your graphics card on the Unigine benchmark Heaven by following this link: https://benchmark.unigine.com/heaven. This is a safer option compared to FurMark, especially if you are not an advanced user.
