"System.NullReferenceException: Object reference ***" error pop up message in Vugen

Hi,

Frequently I get "System.NullReferenceException: Object reference not set to an instance of an object" error pop up message in Vugen which in turns block it and needs Vugen process to be killed.

I remember same issue in previous version of Vugen which was solved through a patch -https://softwaresupport.softwaregrp.com/doc/KM01227949

 

Is there something similar for v12.57 ?

Using same DLL files corrupt the Vugen and right click doesn't work.

 

Thanks,

Girish
