my photoshop freeze as soon as i use the crop function and changing the format !

 I tried with various photos. All other function work fine. What shall I do ? deinstall and re-install the software?

What have you done for all-purpose trouble-shooting so far?
Restoring Preferences after making sure all customized presets like Actions, Patterns, Brushes etc. have been saved might be a good starting point:

I have been having the same problem, I think it's only been occuring since the latest update. Other functions work fine but as soon as I try use the crop function it just freezes.

Could you please post screenshots with the pertinent Panels (Toolbar, Layers, Options Bar, …) visible? 

What are the Crop Tool’s settings?

Thanks for getting back to me but I have just reset the preferences and it is now working ok. A bit of nuisance but hopefully now working again.
