Model Error Code generation file does not exist SIMULINK and ARDUINO

Deer all programmer,
Since last week, I can not continue my experience on simulink, du to an file error I suppose when I try to run any files on my arduino ardware (I use arduino uno and mega)
I try to re-upload Matlab and Simulink or create new files but failure perist.
thanks to your support
