Anyone know why terminal doesn't work?

Hello, I’ve just launched Jupyter lab for the first time and I’m trying to run a script in the terminal. Whenever I open the terminal, it changes to an administrator tab and doesn’t let me run anything. Does anyone know how to help with this? Thank you!

Even i have installed it for the first time and it’s working fine for me.Problem might be something related to Administrator in ur system.
