Issue with loading magni in simulation

General Questions
1

I am trying to run the magni in simulation but I am facing an issue with the image of the magni. For some reason, the magni itself is not being loaded like shown in the tutorial, I am also getting an error for some of the packages not existing.

Hope there is a way to resolve this,

Thanks
