how to remove stry 302

Hello everyone,

I have a coding problem and hope you can help me with it.
I copied part of the code from the Internet and programmed the rest myself. Everything worked out in the beginning and the program worked extremely well. It was only when I programmed a few lines of code to choose game mode that it started showing me error messages.
As I said, everything worked before that.

thank u very much!

here is the error message:

Dieser Bericht wäre detaillierter, wenn die Option
"Ausführliche Ausgabe während der Kompilierung"
in Datei -> Voreinstellungen aktiviert wäre.

The carat (^) is pointing directly at the character to remove
