7) Reinicie al sistema
8) Después de reiniciar completamente, vuelva a la recuperación e instale Magisk zip una vez más
9 ) Reiniciar al sistema
10) Espere totalmente arrancado, abra la aplicación magisk e intente el comando adb shell su para aceptar la solicitud y permitir el acceso a adb su.

Tal vez haya una forma más fácil, pero esta es una forma en que probé que funciona.
