I have been enjoying using Calibre to edit my e-books very much, but I have recently lost three books in the middle of editing.

This is the error message that I am getting:

calibre, version 2.35.0
ERROR: Failed to open book: Failed to open book, click Show details for more information.

Traceback (most recent call last):
File "site-packages\calibre\gui2\tweak_book\job.py", line 34, in run
File "site-packages\calibre\gui2\tweak_book\boss.py", line 56, in get_container
File "site-packages\calibre\ebooks\oeb\polish\container.py", line 1258, in get_container
File "site-packages\calibre\ebooks\oeb\polish\container.py", line 958, in __init__
InvalidEpub: No META-INF/container.xml in epub

I regularly save my work to the original file and it has been working well for over 100 books. now this.

Can anyone help as to why it happens and how I can prevent it happening again?
