Predefined C++ Types (compiler internal) Not Found error

Question

I'm attempting to write a game of tic tac toe just for fun and am running into this error when I try to debug the application. The error occurs on line 23, the multidimensional std::array declaration. I can't find any material on the subject or come up with my own solution. The error shows up in a "Source not found" tab in VS 2019, doesn't look like a normal error, and this is the text: "predefined C++ types (compiler internal) not found You need to find predefined C++ types (compiler internal) to view the source for the current call stack frame."

This is an error of VS. It works when I remove /permissive-. This problem has already been reported.
