  Transport Check: If the app variant was recently transported, check the transport logs to ensure that it was transported successfully and is available in the target system.
  Authorization Check: Ensure that the user has the necessary authorizations to access the app variant. You may need to check the roles assigned to the user and ensure they include access to the relevant app variant.
