Any solution for this?

In your uproject file you need to have the project name

example

{
	"FileVersion": 3,
	"EngineAssociation": "5.3",
	"Category": "",
	"Description": "",
	"Modules": [
		{
			"Name": "yourProjectName",
			"Type": "Runtime",
			"LoadingPhase": "Default",
			"AdditionalDependencies": [
				"Engine"
			]
		}
	],
	"Plugins": [
		{
			"Name": "ModelingToolsEditorMode",
			"Enabled": true,
			"TargetAllowList": [
				"Editor"
			]
		}
	]
}

in your source target files you have to have your project in ExtraModuleNames.Add(“yourProjectName”);

inside of source / yourProjectName/ yourProjectName.cpp
it’s crucial to have the main module set

#include "yourgamename.h"
#include "Modules/ModuleManager.h"
IMPLEMENT_PRIMARY_GAME_MODULE( FDefaultGameModuleImpl, yourProjectName, "yourProjectName" );

Brooooo you just saved my bacon big time. i deleted that module file a couple days ago because i thought it was a file I made on accident then forgot about it! I restored it back from the recycling bin and it booted up just like normal. Thank you so much!

First of all , thank you @3dRaven <3

This is what worked for me in case anyone still has issue :face_with_thermometer:

Deleted temporary files and folders :
deleted

Added ProjectName.h and ProjectName.cpp to ProjectName/source/ProjectName/ (here):

ProjectName.h :

// Copyright Epic Games, Inc. All Rights Reserved.

#pragma once

include “CoreMinimal.h”

ProjectName.cpp :

// Copyright Epic Games, Inc. All Rights Reserved.

include “ProjectName.h”
include “Modules/ModuleManager.h”

IMPLEMENT_PRIMARY_GAME_MODULE( FDefaultGameModuleImpl, ProjectName, “ProjectName” );

then right click on uproject file → generate visual studio project files
and opened solution file and compiled successfully …
no more weird errors

I had a project started up using Lyra and the primary module for the project already had

IMPLEMENT_PRIMARY_GAME_MODULE

So I thought my tangential module didn’t need it. Turns out you need it. Just slap it in the Module.cpp file and use your module class and two random names for it as second and third attributes.

Code in the module worked like a charm afterwards. Thanks!
