can not open odg file

[paulrum]

Using libre office 5.4.4.2 on windows 10
Read error: Format error discovered in the file in sub-document context.xml at position 2,10609 (row,col).

This was a document I recovered from a .pub file I was sent. It opened happily enough in Draw as an ODG file.
I had been working on the document for days, and had no problem saving edits/changes, until I had to reboot my laptop for a Windows Update. I now can not open the file due to the above error message.

I have tried one forum post to save the as a zip file and try finding the error in the content.xml file, but the file will only open in writer or wordpad, and I can not really see / find the issue.

Could I upload the ODG file for some to please help. This document was a product of at least a weeks work, not something I can recreate from scratch.Securenet TECH - Technical Services Introduction.odg

Here is the recovered file. It had a missing attribute name in context.xml like this:

<style:graphic-properties ="nonzero" draw:stroke="none" draw:fill="solid" draw:fill-color="#aecf00" draw:opacity="100%" draw:shadow="hidden"/>

The ="nonzero" part was removed.
