Hmmm, It seems like a permission problem.
You can try to disable AVG Anti-Virus untill restart.
Or you can try to run Visual Studio as Administrator.
If anything above doesn't work you might need to try change the default location of the project folder.
You can do that by:
1. Opening Visual Studio
2. Click the Tools and select Options.
3. Click on Project and Solutions folder and select General.
4. Change the location for Visual Studio project location to your desktop or somewhere else.
