Error Message: None of the rows can be imported

Error Message: None of the rows can be imported

I have been using zoho sheets to download my CSV file for about 2 years now, this month, October 2021, for some reason when I download it to upload to zoho books I get a message saying "None of the rows can be imported". I have been using the same process, nothing has changed.  Was there an update that I am not aware of that I need to make changes so that I can import my CSV bank statement?  Thanks
