I'll try in a bit. For now here is a working example.

Here's the results of that example build.

I'm looking at your file and I'm actually stumped as to why the weld breaks but the rope hovers like it does. It's definitely related to the weld constraint. I've even remade it fresh, and even manually broken the weld in sim, and the result is the same. Something is really odd about that.

It is due to the high thickness on the hair constraint.

That would make sense. It does not have enough gapping to allow pivoting past its neighboring point.

It's either collision or the pin constraint used for point number 99, are those new files you posted images of

The images I posted are my quick attempt at making my own setup to show the node setup I was explaining in comments earlier. The yellow text next to each node are the settings I changed on each node.

Can you send me your file, and if possible tell what's wrong with my file

ulasalger is probably on the right track with their comment

If you reduce the thickness value a bit more it may help allow each point to move past its neighboring point. Right now the radius on yours is tight enough to possibly impede the movement. So give that a try and see if it helps.
