Downloading Source Code - Question

I am following along here: Onboarding Guide for Unreal Engine Games Licensees | Unreal Engine 5.0 Documentation

But after doing step 4 just fine ( 1. Run GenerateProjectFiles.bat to create project files for the engine. It should take less than a minute to complete.

I am unable to do the step following it:

Load the project into Visual Studio by double-clicking on the UE5.sln file. Set your solution configuration to Development Editor and your solution platform to Win64, then right click on the UE target and select Build. It may take anywhere between 10 and 40 minutes to finish compiling, depending on your system specs.)

I’ve attached an image so you can see what I see.

Ok. So I actually figured out that I was just in the wrong tab in VS.

But something slightly confusing…the instructions say that it should take 10 to 40 minutes…mine is taking hours and I have a top system. Any thoughts why this may be?
