Pre-compose is not working when i click on it

That happens when there is an inconsitent logic to your attempt to pre-compose, liek e.g. including mixed layer types with specific dependencies or layer switches. Impossible to say. Unfortunately attachment download is defunct at the momemht, so nobody can look at your images unless you care to re-upload them again and embedding them with the image icon in the post editor, not as attachments.
