C++ hook attach code in Mod Module not running

I have been trying to get this simple function hook to work but I can't figure out why it isn't working.

 cpp
#pragma once

#include "Module/GameInstanceModule.h"
#include "TPRRootGameWorldModule.generated.h"

UCLASS()
class TRAINPATHINGREWORK_API UTPRRootGameWorldModule : public UGameInstanceModule
{
    GENERATED_BODY()
    public:
        UTPRRootGameWorldModule();
        ~UTPRRootGameWorldModule();

        virtual void DispatchLifecycleEvent(ELifecyclePhase phase) override;
};

    //if (WITH_EDITOR) return;

    TPRRegisterWindowsHooks::RegisterWindowsOnlyHooks();

    Super::DispatchLifecycleEvent(phase);
}

I've tried putting logs everywhere and they're not coming through... I put the Declare log category extern and the define log category in the files that the documentation told me to... Anyone got some more insight?

Help needed getting started with modding with C++

I've coded in C++ with unreal before... but it's been a while... So I wanted to get into it again since the trains lacking any decent pathfinding was bothering me. However... I can't for the life of me figure out how to get the C++ part of modding working. blueprints worked fine... but when I generated a new mod for bp + C++ I was unable to get any C++ classes working.

C++ Content folder not showing up

I just made a new blueprint/C++ mod project using the alpakit dev tool. However, I don't see any C++ Classes folder in my content browser. I've followed all steps from the C++ setup tutorial.

Connect to dedicated server with sftp with certificates?

Is there any way I can connect to a dedicated server in the satisfactory mod manager using sftp and certificates instead of a password?
