With the help of such a function, I call the menu.

After watching the video from the menu, the menu stops working

function Untitled_1_Callback(hObject, eventdata, handles)
global videoFReader
faceDetector = vision.CascadeObjectDetector();
videoFReader = vision.VideoFileReader('Eurofighter TYPHOON.mp4');
%videoPlayer = vision.VideoPlayer;
depVideoPlayer = vision.DeployableVideoPlayer;
while ~isDone(videoFReader)
  videoFrame = step(videoFReader);
 step(depVideoPlayer , videoFrame);
end
axes(handles.axes1)
imshow(videoFReader);
 function Untitled_2_Callback(hObject, eventdata, handles)
global EE;
EE
SEPECAT_Jaguar
 function Untitled_3_Callback(hObject, eventdata, handles)
global videoFReader
faceDetector = vision.CascadeObjectDetector();
videoFReader = vision.VideoFileReader('Saab JAS-39 Gripen.mp4');
%videoPlayer = vision.VideoPlayer;
depVideoPlayer = vision.DeployableVideoPlayer;
while ~isDone(videoFReader)
    videoFrame = step(videoFReader);
   step(depVideoPlayer , videoFrame);
  end
axes(handles.axes1)
imshow(videoFReader);||
