Unable to access roles page as admin in Nexus UI

Hi Team

When trying to access the Roles page and when trying to create a Role in the Nexus UI, I am getting - An error occurred loading data. Request failed with status code 403

I have admin permissions and can view and create roles through the CLI without issue.

I have found the following error in the logs-
WARN [qtp156427007-26291] *UNKNOWN org.sonatype.nexus.siesta.internal.AuthorizationExceptionMapper - (ID 4821ce6a-9667-4b34-997a-44aaac9f4865) Response: [403] (no entity/body); mapped from: org.apache.shiro.authz.UnauthenticatedException: This subject is anonymous - it does not have any identifying principals and authorization operations require an identity to check against. A Subject instance will acquire these identifying principals automatically after a successful login is performed be executing org.apache.shiro.subject.Subject.login(AuthenticationToken) or when 'Remember Me' functionality is enabled by the SecurityManager. This exception can also occur when a previously logged-in Subject has logged out which makes it anonymous again. Because an identity is currently not known due to any of these conditions, authorization is denied.
