Hello, I apologize for my level of English because I'm not very familiar with this language.

So here, my problem is that I can't open one of my projects on Krita, krita say "Not a Valid file" I tried to change the .kra in .zip and then repair the zip file with Winrar and Zip Repair Pro. It works but when I open the file there is nothing in it while the file weighs 5MB when i try to open the repaired file krita says that maindoc.xml is missing.

For information I had no problem of crash in the software, computer or other. Similarly, I do not have an autosave of the project (idk why)

So I come to you in the hope of being helped. I put you the dropbox link of the file : https://www.dropbox.com/s/ewr28w2cjqw9uy4/lupus.kra?dl=0

I thank you for any help.

I cannot repair the file here either, it remains empty. What I would suggest at this point is to see if you have a backup file, these end with ~(so lupus.kra~), rename that to remove the '~' and it should have the file just before the previous save.

Yes... All bytes are 0 in this file. I have no idea how that could have happened
