File format error found at saxparseexception

I've saved a docx file with LibreOffice and I can't open it now.
The error and the docx file are attached. Can you please help me?

I'm not getting anywhere with repairing this file; from inspection I have the feeling that it is utterly corrupt, one section of internal code being repeated multiple times. I am not seeing any meaningful text content.

Edit: I strongly suggest you immediately try the following: You may be able to recover a previous version of the file - see [Tutorial] How to find and un-delete AOO temporary files for detailed instructions on how to a) use Previous Versions (W7 and later) to recover previous versions of the file ; b) recover your file as it was when you last opened or saved it, or as it was when it was last saved with AutoRecovery; c) find previous versions of the file in the folder it is located in, but which have since been deleted; d) un-delete the temporary files AOO wrote while you were editing the file, and then deleted. This will recover your file as it was when you last opened or you last saved it.
