Steps to reproduce

1. Go into a deck, click export
2. Choose mochi format, exclude review history, exclude subdecks
3. Exporting asks for a place to save the export
4. check the place, click save

Expected behavior: Mochi will export the deck in .mochi format to the chosen location

Actual behavior: the file is saved, but is empty. Mochi with a few seconds delay says "Adding files" and then gets stuck on it, never stopping to run, needs a hard reset of the app to stop it.

System: Android Tablet Xiaomi Tab7, running Android 16 as HyperOS 3.0.3

Tried multiple times, same result always.

Workarounds: export as Markdown is working, but would result in a .zip that will give you single .md files for every card. Would make it necessary to import every single card separately, cause cannot add a whole folder at once.

CSV haven't tried yet.

Actually, if you want to backup or send your deck and include your review history, mochi format would be obligate - so I think it's necessary to fix this as soon as possible.
