If Jonas had his laptop with him that day, I assume he worked on an M1 Max MBP. I have tried to reproduce it on the same model and also checked different releases. Somehow I run into the same problems as I believe you do.
Please set up everything as he does (Leave Gravity as is for now), but try to increase the Sphere Field; that did the trick here.
Here is my "follow along" file; while having also explored all options, I assume that Sphere Field adjustment is the way to go.
Image has SDS on it (default settings)
If your problem is not solved, please share your file here. I'm happy to look into it, and if needed, ask Jonas directly next week.
I found to rotate the Torus a little bit (R.H, animated) allows for better folding.
My best wishes
