Sorry for not responding sooner! I'm playing it on Windows 10, using the Windows version of course. I'm pretty sure I'm using the full game, the version released on August 23rd. I'll try redownloading it again and making sure I have the correct files!
Edit: So I did that. It started up like it has been, showed your credit, 'LOADING', then came to this: https://imgur.com/a/7Ey82wB . And it stayed there, I just seeing what I knew was the moving starting screen but blurred and not interactable. I waited at least 15 mins and tried clicking a few buttons but no avail.
