I had similar problems with update win 10 build 1803 and Excel 2003. Fix was as others (Charlie) said to go back to Build 1709. In my case 6-7 hours of looking on the web & trying things which did not work. Very frustrating and a big waste of time.
In my case Excel 2003 & build 1803 seemed to work in general. However when I went to certain cell and changed the date Excel 2003 crash & saved the data like someone said. In my case, the cell/row was protected which I unprotected, but it still crashed every time. I had like 20 pages of related & referenced cells and macros. Could not figure out problem as I did not code the Xls spread sheet I just know build 1803 crashed every time. Problem relates to excel 2003, MACRO SECURITY, and protected cells.
As I said my fix was going back to Build 1709. Thanks to all above.
