Short description of error
Been experimenting with QuadriFlow quite a bit to see what it can and can't do. This time I tried it on a mask extracted mesh I made, which did not create very nice looking results (I was expecting it to look more like a quad loop when remeshing). However, I noticed that QuadriFlow crashes pretty regularly on even low poly meshes if you type in specific numbers that it can't create a new remesh out of. In my case, when I typed in 40-43 on my extracted mesh, it did not crash. However, once I reached 44, the program failed every time and simply died.

Exact steps for others to reproduce the error

Here's a file of the mask extract mesh. You can begin typing 40 faces into QuadriFlow to see if it works or not. If it doesn't crash, just type in another low number and keep trying until it does.

Here's another strange thing I found regarding QuadriFlow when using Paint Symmetry. You get far better quads when it is active, but you can't get a perfect loop that matches the original model. When it is inactive however, the results become completely unusable.

This is because the mesh you are trying to remesh is non manifold.
