For some reason, the “Release” and “Remove” options are both grayed out in the Virtual Media Manager.

I am trying to remove a virtual hard disk from my primary solid-state drive in order to free up space because I am low on disk space.

Thank you.

Not for "some" reason, but for a very specific reason; it has "children". Do you see that triangle? Open it and see the dependents of that file that you want to remove.
