Unity closes when using the cloth component

Unity simply closes every time I try to remove a cloth component from a GameObject.

It also happens when I select some vertices, the editor gets extremely slow and unity begins to work in a strange way. Has anyone had this or any suggestions?

Unity 5.5.0f3.

Yes I had seen that.

My unity 5.5.0f3 closed when I tried to remove a Component called cloth.
And also the cloth with the component work in a very bizzare shape!
Can’t believe it. The cloth exploded like a huge spike ball.
