Thank you for posting this issue.
In Valentina can you select 'Help', 'About Valentina', and post the version of Valentina that you're using?
Are you using Mac, Windows, or Linux?
Can you list the steps you took before the error happened? Was there an error message, or did Valentina unexpectedly crash?
The file you posted is empty, which means it lost all of it's contents
