Is there anyway I can recover those files?
Hey @Jenjira_Kitwakin1 , do you happen to have emails from your university email address forwarded to a new email address? If so, we recommend to reset your password so that you can surpass the Google single sign on login to access your Figma account, and then update your email address as needed.
If not, please reach out directly to the support team by filling out this form for further assistance: here
(or I can create a support ticket on your behalf, please share your new email address via MP). Thank you
