bug – Read .iwa files from Pages

Pages has crashed, my file is now corrupted and I’m trying to get the text from this file.

if I Right click on the file > Show package content > open index.zip , I can see a bunch of .iwa files which seems to contains my original text, especially “Document.iwa”.

If I “$ nano Document.iwa” (because “$ file” only returns “data”) I can see some of my text, but the overall seems crypted.

Does anyone know how to decode/read this kind of .iwa file or recover corrupted files?
