Reinstalling numpy did not work for me.

I had the same issue and noticed multiple paths pointing to numpy in the error message. E.g.

I deleted the C:\Users\USERNAME\AppData\Roaming\Python\Python37\* folder because that was left behind by a previous Python which I had uninstalled. I would not recommend deleting anything until you are certain you won't break other things, so maybe send it to the recycle bin and restore if it does not fix the issue for you.
