Since you are selection "Personal Account" option to login, that means you are using your Adobe ID (not Federated ID).
Since you are not able to view the Workspace projects created or shared by you, that means the projects are associated with your Federated ID. You can use "School or Company account" option to log into Experience Cloud (and then navigate to Analytics). With this method you will be logged in via Federated ID which does not require a password to login.
Hopefully, you will now be able to access the Workspace projects. Let me know if this helps!
Additionally, you can check if you have Workspace access associated with your Adobe ID account. This can be done via Admin Console which only system admin users can access. So if you are not a system admin user (not Analytics product admin) for your organization, you can reach out to an existing system admin user to get your access updated/checked for Adobe ID.
