Case denied after RFE submission

I received my RFE in late March. Response was supposed to be received by USCIS by June 20th. My lawyer submitted the response very late like June 16/17. I was concerned that my RFE response won’t be received in due time. I kept checking case status but no change other than the previous update “RFE was sent bla bla” Today I checked and its denied. My case was regular processing so a decision this quick I’m assuming the case was not received by due date? If it’s a lawyer fault how do I deal with this? Please help. My PD May15,2024. TSC. Regular
