Document automatically closes

Every time I open an existing file, a curriculum, for example, editing it and go from nothing closes the program alone, and the image 1 appears, and a file folder in which this curriculum was (.lock.curriculum.docx~#.)

I click OK and the program stops responding, I have to finish it by Task Manager, I try to open again and this image 2 appears. I click Start Recovery, it retrieves the last change made (without my changes) and the whole process repeats: Close of nowhere> Ok> Lock> Manager> Close> I open a new> Recalls> Close from nothing …

Hi Filipe Manuel.

Have you tried saving it inside Microsoft Office as an ODT file format?
The option to save a document as a LibreOffice file format exists since version 2007. (For Office 2003 users check SUN ODF Plugin).

Maybe there is some .DOCX feature that it is yet not fully compatible. Maybe. Hope this helps you out.
