Have you tried the vulkan version?The dx12 build can be a bit hit or miss.
Deleting the "shader_cache" and "vulkan" folders might fix the vulkan build.
On windows the folders are at: %appdata%\Godot\app_userdata\HardStuck\
On linux the path is: ~/.local/share/godot/app_userdata/HardStuck/
What model gpu do you have?You could also try to run the game from the command line, there might be an error message there that could help figure out what the problem is.
