Hi, when I open my affinity publisher file, after a couple seconds I receive the error message "The file is damaged and has to be closed now" and then it closes. I tried it on several computers and instances, it's always the same. It's an important project that we worked on for more than two months and was supposed to be printed tomorrow! I would really appreaciate help from support as fast as possible. Please send me a private upload link for the file.
