Can my former landlord ask for money after I've left the property?

Hi, I was living in a flat as tenant from 2018 November till 2023 January. I paid the rent every month as agreed from 2018 November till 2020 July. Then it was pandemic time and as I work in tourism sector in India I lost my job and there was no source of income for my family till 2021 November. We struggled a lot at that time and we were unable to pay the rent of that period. Then again from 2021 November I started paying like past. We told our landlord who is a central government employee that with the current month's rent we will be adding some more money and pay the due rent of the period we couldn't pay. But he increased the current rent to a big amount and kept pressurizing us to leave his house from 2022 February. We pleaded to cooperate with us as then we were not in a position to pay for a house shifting then finally we left his property on February 2023. In all these months we paid the current rent only. Now after a year of leaving his home he is coming to our current home and humiliating us and asking for the accumulated rent. My question is (1) Can he ask for the money now, after we have left the property for not being able to pay the rent and while we left he didn't say anything and he was pleased with the fact that we are leaving? (2) Currently we are living in a different rented house and it is not possible for us to him the huge money he is claiming, so what can I do now as I and my family are very disturbed by the humiliation they are creating?
