URGENT - Immediate crash when saving [RESOLVED - by resetting the preferences]

So, I was having no trouble at all with my project until about 30 minutes ago, and now everytime I try to save any file it crashes! I just can’t save anything anymore! I trie creating a new file, in a new folder, saving as, saving a new version…

But as soon as I modify anything even in a new project, Harmony crashes!

Any idea? I have work to do!!!
