I used to be because of a misdiagnosis and it was hell. No, it didn't help with autism issues, it actually made the sensory and social issues worse because I had no energy to use my coping strategies.
But it made me too weak and dumb to express it.
I get it that one can have a psychosis along with autism and then it possibly could help. But beware - my case wasn't unusual, meltdowns confused for psychotic episodes, shutdowns confused for schizophrenia - it's too easy to wrongly diagnose psychosis in an autistic person.
And my personal opinion is that giving risperidone to autistic children should be highly restricted, only after proving actual psychotic disorder (not as a meltdown-stopper).
