Can't open auto-save version. It gives me the message: "Data invalid at root level. Line 1. Position 1".

I had saved the xdlxliff file before needing to restart my computer but file did not save for some reason now I've lost half of my work and the auto-save version doesn't want to open. I've tried restarting Studio and renaming the auto-save file name but nothing is working. I urgently need help on this as my client needs the file soon. what can I do please, I find nothing inside the knowledge base that could help. Thanks!
