Unknown Exception Encountered: What does this mean?

I installed TurboTax Deluxe a while back, no problems.  I install updates, no problems.  

 

After an update the program opens, no issue, but many times when I close it the following screen.  Does anyone have any idea what this means?   I have only entered very preliminary information into TT at this point, but wish to start working on my taxes next week.   I don't want to encounter any problems.   

 

Screenshot attached.  Thanks in advance for any help.
