Error saving file

I started getting the Following error saving a specific file for Libreoffice 5.1.4.2:

Error saving document xxxxx
Error in writing sub-document context.xml

I upgraded to Libreoffice 5.4.6.2, but the problem still occurs. This would occur for any file I opened and tried to save. The file size is 58354305. I upgraded to LiberOffice 5.4.6.2. The problem still occurs for the large file. I am able to open and save other files.

Anything I can do to be able to save this file again?

I updated to 6.03 and the problem went away.
