Rebuild (with hot reload) fails on newly-created projects

Performing a Rebuild with a hot reload on a brand new code project will fail unless both the Editor and Visual Studio have first been closed and then re-opened. The same result occurs if a Clean is attempted.

This was only tested in a binary build of the Engine, since rebuilds of a source-built Engine rebuild the entire Engine.

REGRESSION:
Yes. This behavior did not occur in 4.17.2

1. Create a new code project using the Third Person template.
2. Once both the Editor and Visual Studio have opened, right-click the project in the Solution Explorer window in Visual Studio and select Rebuild.

RESULT:
The rebuild fails with an error similar to the following: error : Unable to delete D:\Unreal Projects\Current Issues\TestRebuild\Binaries\Win64\UE4Editor-TestRebuild.dll (Access to the path 'D:\Unreal Projects\Current Issues\TestRebuild\Binaries\Win64\UE4Editor-TestRebuild.dll' is denied.)

EXPECTED:
The rebuild completes successfully.

WORKAROUND:
Close and then re-open both the Editor and Visual Studio. A rebuild with a hot reload will now complete successfully.
