Unable to compile project in 4.19

[ConantBC]

It successfully creates a Haxe directory for my project. However, I am unable to compile my project. Attempting to build from within Visual Studio creates the following output:

It looks like there are a bunch of member variables in the wrapper classes that are defined in Haxe/Externs/Common that are not in the 4.19 version of the engine.
