UE4 Visual Studio MSB3075 Error

Hi, I was working on my UE4 C++ project.
I am using Visual Studio 2017

yesterday all my files compiled successfully and saved in my repository
However, this morning I got so much error in all my files related to Battery Collector,
(Character, Gamemode, Pickup files)

I was following the video posted on youtube.
I even opened my Visual Studio in Administrator mode, but it does not solve my problem.

Please Help me the figure out this problem

Thank you
