I use mujoco emulation but swift is automatically invoked without mujoco's emulation interface appearing。

I think I need to use mujoco, but when I use this library, I call swift, which causes me to not be able to use mujoco normally, and the trouble is that I don't know how to cancel this default backend. Mine is python3.8, ubantu22.04, directly pip install mujoco and roboticstoolbox
