Hi, Maya, you are the same person I have been talking to on patreon, right? anyway for anyone who might find this answer and have the same problem, I'm afraid I can't be of any help. I suspect it may be a compatibility issue, TU Project uses DirectX 12 as the only RHI to make use of Lumen and Nanite, so computers that are not software or hardware compatible would not be able to run the game.
I'm sorry ＞﹏＜.
