[C# console app .net4.7.2] Seemingly can't instantiate an object

Okay So I'm working on a text based adventure app for an entry level college class. I have an "Alien" base class which is inherited by a "CrabAlien" class, I'm trying to instantiate a crab alien in my "GameWorld" class but it's telling me that none of it exists in the current context and I'm not sure why.

Query Rider TODO etc. comments for a solution, project, or file into console output

The TODO list Tool Window is very useful, but I would very much like the ability to pull that list into a markdown file as tasks for an Obsidian markdown note. Any ideas on how to do this, or must I copy the TODO patterns and filters into my SourceReporting Roslyn based app and apply the filters to all comments in a CSharpSyntaxNode or something?
