Hi Reily,
I'm Brad from the Product Team - I appreciate you reaching out and apologize that this hasn't worked for you today.
Our team has done some initial investigations today and can see that it's failing when trying to create the synthetic dataset, but aren't exactly sure yet what's causing the failure. I do encourage you to try again, and am optimistic that you have better fortune when you do, but if not please reach out. In parallel we will continue our investigations. Feel free to reach out directly via DM or email if you have any further issues or any questions.
Thanks,
Brad.
