Qué significa que SecTaskLoadEntlitlements falló error=22

Estoy intentando ejecutar un juego que he comprado en Steam: Dread Out. Se inicia la pantalla principal, las opciones, etc. pero cuando voy a jugar el primer nivel, no carga el nivel. La pantalla de carga se queda para siempre, con la música y los consejos. La aplicación parece estar funcionando pero no se carga ningún contenido ni se envía ningún error. He puesto un indicador en la consola y me aparecen los mensajes mientras se ejecuta la aplicación:
