SAXException error. Anyone with experience available to help me fix it?

Using Libre Office 7.4.6.2

When I go to open a docx file I spent hours creating I now get this error:
An error occurred during opening the file. This may be caused by incorrect file contents.
The error details are:
SAXException: [word/document.xml line 2]: Opening and ending tag mismatch: rPr line 2 and ins

Proceeding with import may cause data loss or corruption, and application may become unstable or crash. Do you want to ignore the error and attempt to continue loading the file?

If I choose yes I only have one page out of the original 18-20 pages I created. If I choose No I get the following information:
File format error found at
SAXParseException: '[word/document.xml line 2]: Opening and ending tag mismatch: rPr line 2 and ins
', Stream ‘word/document.xml’, Line 2, Column 33774(row,col).

It looks like it’s telling me where the error is. I followed other information on this site to find out that I can open the document file after turning into a Zip file but then I don’t know how to find the error and correct it. Anyone here who can do it for me if I send you the file? I can even send you a Venmo tip for your time if it works! :slight_smile:

5h later, was that solved in private ?

if not, send it over.
(and no venmo)
