Problem with C++ and Visual Studio 2019: The document cannot be opend

[Logitechnological1245]

I'm having a problem with my project in Visual Studio 2019. I'm making a game using SFML. When I try to open a file...lets say GUI, I'm coding the GUI for my game. I get the message The Document cannot be open. It has been renamed, deleted or moved.

I haven't written anything in it yet.

From your description I didn't really understand what the problem is.

What you do what exactly does that error appear? And where does that error appear? When compiling? From Intellisense?

Its appears when i try to open it in the solution explorer in visual studio. And it already has happend with more then one file.

Well does the file exist on the file system?

Either way, this doesn't exactly seem like anything related to SFML, so you'll probably have more luck with a simple web search.
