Should GSTR1 and GSTR3B be filed after cancellation?

Hi,

I applied for cancellation of GST registration on 14th July, 2021 and got it approved by 22 July, 2021, with effective date of cancellation as 14th July, 2021. After that I filed the GSTR-10 final return on 23 July, 2021. 

Should I file GSTR1 and GSTR3B for July month which have deadlines on this August month? I have this doubt because some days of July have passed before the effective date of cancellation, that is 14th July. Please help me in this doubt.
