title: In Spring Tool Suite 4, when creating a Run Configuration, the Project dropdown menu does not display any project. "No project selected"

  In Spring Tool Suite's Run Configurations, there is an option for Spring Boot App. There is a dropdown menu meant to select the project, but currently there are not any options available. I seem to have a problem selecting a project, but I cannot find where to &quot;select&quot; a project if the dropdown menu does not display any options.</p>
