Moving a Visual Studio project from a different computer?

Question

I am using Visual Studio 2019, and I am trying to open a project sent by my friend. However, when I tried opening the solution or the project, this error shows up:

An error occurred in '[Unknown]' while attempting to open <filename>

File path: (The path from my friend's computer)
Frame GUID: 
Frame mode:
Error code: 0x80004005

I have tried to change the file path, but the file path is correct in my computer, so what is this file path referencing to ?

Answer 1

Close the solution, then delete the folder named .vs (note the dot) in the project directory and restart Visual Studio. This folder contains cached data that's computer-dependent.

You can also just close the window with the error and reopen the file from the solution explorer.
