Ich habe ein Python -Programm, das ich in VSCODE ausführe, aber irgendwann erhalte ich diesen RuntimeError: Ich kann bei Interpreter Shutdown keinen neuen Thread erstellen und ich schließe nichts, ich verstehe nicht. Und übrigens funktioniert das gleiche Programm auf meinem Freund Computer (wir haben genau das gleiche) < /p>
Code (Entschuldigung, es ist ein bisschen lang, aber ich kann es nicht kürzer machen, ich habe bereits alles ausgeschlossen, was nicht wichtig war): < /p>

Der Fehler findet nicht statt, wenn ich das Programm starte. Die Clients und die Websites werden beim Start gut geladen, aber wenn ich versuche, den Client während des Klickens auf den Taste Self zu laden.>
