Latest WhatsApp backup is not available

I have backed up by WhatsApp data atleast until September 15, 2020. I deleted WhatsApp and reinstalled it as suggested as the search function was not working. After re installing my data is recovered from a back up in January 2020 but not from the latest back up in September 2020. I want to recover all the data. What should I do?
