For help on a specific game, it is always best to check directly on that game's page.
What you describe does not seem to be an error in the download, but rather in the execution of the game, and from what I have read in other posts, this game only works with vulkan, if your GPU or your drivers do not support the vulkan version of that game, it will not be executed.
I have never seen the developer answer a single question here, but once he answered the moderator indicating that he did support his game (this forum had many posts from people requesting help for that game), so the best thing is Look for the contact information in the game or with the developer and ask for help that way.
