Error reading content.xml

Solved
Hello everyone,

I can no longer open a LibreOffice file.
Here is the message

" read error - format error in the file of the sub-document content.xml at position 2.719029 (row, col) "

I have seen several forums and understood that it was due to a failure of my USB stick (or something of that kind), but I can't seem to solve the problem.

Could you please help me?

Thank you Thank you!
