"Sticking" occurs in collision constraint solution
Two rectangles collide, use the following formula to calculate:
$$
J = \begin{vmatrix}
J_{1} \\
J_{2} \\
J_{3} \\
\end{vmatrix}
$$
$$
J_{n} = \begin{vmatrix}
\overrightarrow{n} & \overrightarrow{...

Why doesn't multi-constraint work in this case?
The situation is as follows:
