Welcome to the community, @sai! Maybe you will need to follow the instructions as discussed previously:

Export Failed Error

Here is a post discussed previously on why you get this type of error (it should help you solve your issue): Steps to solve your issue: Download your xlsform (different deployed versions) by cloning them. Check the differences (especially focus on repeat group questions). Identify the changes and edit the xlsform accordingly. Replace the xlsform and redeploy. You should be able to download your dataset without any issue.
