Can't save target file on Trados 2017, please help!

Question

I was not able to 'Save Target As' The error message was: FAILED TO SAVE TARGET CONTENT: OBJECT REFERENCE NOT SET TO AN INSTANCE OF AN OBJECT. 
 I was working on a excel file.

Hello CHANDRANIL MANDAL 
 Could you let us know which version of Studio you are using please, along with the Windows and Office version. 
 As the error message is very generic, it would help if you could also post the error stack-

Trados Studio > 1. Trados Studio
