Project is empty, XML is not effective

I did some work by Gantproject. But, when I open it, the project is empty and there is information showing that the XML is not effective. Could you please help me to fix it?Working list_Yu-Fen_20220711.gan (24.8 KB)
Thank you!

Hello,
there are invalid contents of notes in some tasks, probably exotic line breaks or something like that. This sometimes happen when you copy/paste text from other programs, e.g. Word. I replaced those invalid symbols with spaces, now everything is fine. The result is attached.
