MS- Word Error Expected white space error on ms word .docx document

Hello Experts,

I am cannot open my MS-word.docx document.
The error it get is White space expected:Part:/word/docment, XML,Line,2 Column:642733.

I’ve tried everything I can think of! Including:
Saving it as a .zip file. Which it won’t
Saving it as .txt: Which It will- But no help.
Looking at it in word pad: Still no help.

How can I find:,Line,2 Column:642733. and correct it? or at least save what Ive written to that point.
I have no idea what happened to cause this other than the flash drive didn’t update on my last save…

Please please Help.. hours of work were invested….

Thank you
