Why am i getting this screen on my engine?

My game says my game was built on another version and or missing content but i have not touched the engine or the files

Read before going to answer. If you do not have Visual Studio, that could be the problem as Unreal Engine requires Visual Studio.

Answer?: I read this other [answer][1] on another post, and it says it could be your antivirus affecting your Unreal Engine files. Please add your Projects folder and your Engine folder to your antivirus exceptions list.

Directory: C:\Program Files\Epic Games\UE_4.25
The other directory is your Unreal Engine projects folder (Where ever you keep your projects.).
