Xcode File Error

The path has been coloured out because of privacy reasons.

There's not much to go on here - tell us which specific file is missing, from what?

I don‘t know it myself. This popped up when I tried to open the Project File

project.pbxproj is a key component of your Xcode project that contains all of the information pertaining to your build phases, build settings and source code file setup. It resides inside of the Xcode project package (the .xcodeproj file you see in Finder). If you're not sure what happened, you should restore your project from your source control repository or system backup.
