Hello Ankit Kumar,
Thanks for your question.
No, there is no policy that prevents use of business emails.
Can you please retry in an InPrivate Browser or Edge?
If this does not work, maybe try using an alternate email address temporarily to create the account and then add your business email as an alias once the account is set up
You can mark it 'Accept Answer' and 'Upvote' if this helped you
Regards,
Abiola
