IPad version crashed and changed audio

I just had a weird crash on my iPad.
I noticed the application stalling, I tried to save (export), but this wasn’t possible anymore. I then closed the app and reopened. I had lost about the last five minutes (only). I started reentering the notes, that were gone. Weird thing: the sound for the line I was inputting music in, sounded an octave lower… and with probably a different sound, I don’t know.
I remembered to create a diagnostic report, may be already too late?
To find the file I went to the dialogue again, where it shows the place the file will be stored. I am afraid by just looking there, the file must have been overwritten again…
Anyway, I’ll attach it here:
Dorico Diagnostics.zip (742.5 KB)

Thank you for having a look into it.

It looks from your diagnostics that you had somehow managed to open and work on a project that was already in iCloud Drive’s “trash” folder (which is where recently deleted files go for a while before they are eventually actually deleted). I’m not sure how you managed to do that, but when Dorico was trying to save the project in there, iPadOS was (correctly) refusing to let it. There are no actual crash logs in the diagnostics you’ve provided.

Hopefully this was a one-off problem. I would recommend updating to the just-released 5.0.20 update as well.

Thank you Daniel, I will go and get the update later today.
I never trashed that file I was working on (which would anyway only be possible via the Files App) - but it closed by itself a couple of times, while I was trying to change things in the Project Info window. The project just closed and I had to reopen it.
