After a fresh install of Fedora 40 I found some editing programs were not populating in the Applications menu.

I finally tracked the problem down to missing "OR" tags in /etc/xdg/menus/applications-merged/multimedia-categories.menu
This is causing programs tagged with the "AudioVideoEditing" category in their .desktop file to not populate in the Applications menu.

         <!-- Editors Menu -->
         <Menu>
            <Name>Editors</Name>
            <Directory>multimedia-editors.directory</Directory>
            <Include>
               <And>
                  <Or>
                     <Category>AudioVideo</Category>
                     <Category>Audio</Category>
                     <Category>Video</Category>
                  </Or>
                     <Category>AudioVideoEditing</Category>
                     <Category>X-AudioEditing</Category>
               </And>
            </Include>
         </Menu><!-- End Editors Menu -->

Encapsulating the "AudioVideoEditing" and "X-AudioEditing" categories in an additional or block  resolves the problem.

               <And>
                  <Or>
                     <Category>AudioVideo</Category>
                     <Category>Audio</Category>
                     <Category>Video</Category>
                  </Or>
                  <Or>
                     <Category>AudioVideoEditing</Category>
                     <Category>X-AudioEditing</Category>
                  </Or>
               </And>
