This means, In construction function of a class, you are trying to get a value from array at index 1, but that array has only one value at index 0.

To solve this, edit source code and build/compile with VS Community once, then your project will be opened.

It’s like Ravi80335 says, there’s a class trying to access an invalid value from an array in his constructor. Search the last log (Saved / Logs), before the errors you will see the cause of the problem.
