Dear Kanchana Palani,
Good day! Thank you for posting to Microsoft Community. I am happy to help you
Please contact the owner of the form to see if anyone is sharing the link, if not, we recommend switching to anyone and then share the link to see if you can open it:
If you still can't access Forms, there may be a problem on the server side. I kindly recommended you can contact admin user to raise a service request in Microsoft 365 admin center, which the support there has the related permission and resource to help you check from the backend
Thanks for your cooperation.
Sincerely,
Tin | Microsoft Community Moderator
