All of my drawings have disappeared

While I was working on a project, the software suddenly crashed. When I tried to reopen it, I found that all my drawings were missing, although the frames were still visible in the timeline. This issue also affected some of my other Harmony safe files, which was confusing because I wasn’t working on them at the time.
Furthermore, I noticed that my palette list had also vanished, adding another layer of frustration to the situation.
I cannot belive this is haappening, what a complete nightmare. If anyone can help, it would be greatly appreciated!

Go to the folder with the files and find your project file “name.xstage” make a backup of that one and remove it from that folder, then see if you have a “name.xstage~”, remove the “~” and open that file, see if solves it.
