TurboTax Keeps Closing

I am using TT Premier on Win 10.  The program is very unstable and keeps closing, typically when I save a file, or open or close a form.  When I reopen, my file has to be "recovered" about 50% of the time.  I have given my OS a "fresh start" and reinstalled the program, without any improvement.  Any suggestions?

 

Thank you,
