GUI STUCK after Save Tool from GUIDE

I have been working on an gui developed using the GUIDE in Matlab. The current gui, I mean the general figure window contains all types of sliders, buttons, editboxes, etc...

After awhie, I added a toolbar to my gui which included the Save tool. I have not changed any specifications regarding the save tool. I used the one already in GUIDE toolbar editor.

After clicking it my gui program is stuck at that very instance I pressed the save tool and I cannot do anything else with it. It also opens in the same situation even after restarting the PC. I used to get some errors but they stopped and everything seems fine but gui is still stuck.

I would appreciate any help.
