I have somehow made my Project Navigator red and I can't seem to find out how to get it back to normal.

I'm using Xcode Version 14.2 (14C18).

Does anyone know how to fix this?

I have tried googling the issue but I only seem to find the problem where the file name turns red which means the file can't be located by Xcode.

Rebooting macOS, without reopening windows, solved the issue.
