Firebase Database no obtiene datos de Firebase Database Reference

Question

Todo está funcionando bien, pero DatabaseReference no está obteniendo datos, es como simplemente ignorar mi código para ejecutar y como si mi Internet no funcionara, por favor ayúdenme. Soy nuevo aquí en esta comunidad. A continuación se encuentran mis códigos e imágenes.

Anteriormente estaba funcionando, pero como acabo de cambiar un código para hacer solo currentVersion> = vCode para que el usuario pueda continuar incluso si el valor en la base de datos es <currentVersion pero, después de compilarlo, mi aplicación no obtenía datos de firebase y lo intenté para desinstalarlo, instalado nuevamente desde Play Store, la versión anterior tampoco estaba obteniendo datos, por favor ayuda. No sé qué mal hice. Por lo tanto, estoy planeando instalar ParrotOS, así que tal vez funcione, pero es mejor preguntar primero a los expertos.
