Hi there,
Sorry to hear that you can't get into Photoshop as it won't let you sign in.
Which version of Photoshop are you using? Are you launching Photoshop from the Creative Cloud Desktop app? Are you getting any error message while you attempt to sign in?
Would you mind checking the steps mentioned in this article https://helpx.adobe.com/manage-account/kb/account-password-sign-help.html and let us know if that helps you log in?
Thanks,
Akash
