There's no question here.  What are you asking?

can't uninstall extension

Ok, thanks for the screenshots

Generally, this is what it says - it's in the process of installing an app already, so other installations and removals are blocked.

This should not last more than a couple of minutes though.  Do you get the same if you try again?  Could you test by adding another app (a small one that you don't intend to use) and trying to remove that as well?
