Hey there @helder_1! Welcome to the community! This forum is primarily geared towards helping developers using Unreal Engine, and it seems like you may have some issues with a built game. Since this forum is mostly geared towards aiding developers, many fixes that I could recommend involve having the source files to the game. It’s recommended to report the issue to the developer, as they would have more access to correct issues.
My first recommendations without knowing your hardware would be to update or clean reinstall your graphics drivers, as this seems like a rendering error.
