Custom Post Types Permalink Settings, Landing Page

So, I’m new to custom post types, so pardon if this comes across as confusing…

I’m currently trying to set up a ‘landing page’ for a custom post type

My friend wants to make a small site that lists all the albums he has recorded on….

So the custom post type = Albums with a few fields such as title, year etc.
I have the Permalinks Set as ‘/%category%/%postname%’
so pages look something like this https://www.site.com/albums/album_name
this works perfectly.

the problem I am facing is if I go directly to the category (www.site.com/albums) WordPress returns NOT FOUND

I’m not sure what to do here…

Is this something I have to define with the custom post type?

here is my code…
