I am trying to create a new blank C++ project with UE 5.1 like the image below:

But after pressing the “Create” button, there is a pop-up message showing like this image:

If I change the project name “Engine” to any other name ex: “Engine5”, I can create the project without any problem.

I am also trying to google but nothing says about project name restriction .

Is this a bug or did I do something wrong?

You can’t call it Engine. The actual engine (Unreal Engine itself) is also called Engine, and this causes issues.
You can name it “EngineProject” “EngineGame” “EngineTesting” or basically anything so long as it isn’t just “Engine”.

This is the answer. But I want to know is there any other name that is restricted?.
