iPad: Black overlay freezes during export

[ragleb]

How to reproduce:

1. Select the animation frame you want to export.
2. Tap the three-line menu → Share.
3. Choose PNG format and set Resize to x16.
4. Export via AirDrop (I exported it to my computer).
5. After the frame is sent successfully, the app does not return to the UI. Instead, a black overlay remains on top of it, with a yellow bar and the message: “Almost done, wait a little bit.” It cannot be dismissed in any way — the only solution is to fully restart the app.
