What I typed was

]add Pluto

Or is Julia case sensitivity??

Julia is case-sensitive but your command looks fine. Maybe you could share a screenshot of your console?

I’ve also tried it Julia 1.7.2.

]

add Pluto

It then does a lot of positive things, but then errors right at the end:

Pluto is therefore not installed. The folder is empty now, though.

Looks like a bug to me. It says it’s trying to delete some folder in a temporary directory but errors because the folder isn’t empty. My guess is that something messed up your environment.
I would guess that it’s probably fine to delete this directory on your own and try again (it says it is a temp folder after all).
But first I would maybe try installing in a fresh environment:

] activate temp
add Pluto

If that works you should maybe consider cleaning up your main environment. Hope that helps
