  Causes:
  
  Missing Implementation: The class that is supposed to implement the required functionality is not available or has not been properly defined in the system.
  Configuration Issues: There may be configuration settings that are not correctly set up, leading to the system being unable to generate the required instance.
  Transport Issues: If the system has recently undergone a transport of changes, the required class may not have been transported correctly.
