All tasks deleted from a project upon opening

[aaronams]

I've been building out a new project. Yesterday, I opened it and received a long error log and all the tasks are missing. The Resources still exist. I'm using the paid cloud version and will attach what is left of the file, plus my last locally saved copy before the issue, and the error log. Happily, I saved a PNG export recently so can manually rebuild it, but and this could have been catastrophic.

FYI I found the history function in the GanttProject Cloud and it worked perfectly to restore the file.

Since you're using GP Cloud, is there a version where this issue can be reproduced?
