Additional context

Unfortunately it reads like the file hasn't finished saving when you closed the app.

We should definitely fix this by blocking closing the app while a save is in progress.

If there is really important content on it, you could try recovering it through a gzip-recovery tool because the save file is just a gzip archive which contains json data. If it is possible to recover the partially written document then it might be possible to append missing data to it to be able to import it again.
