Steps to reproduce

1. Open gallery app
2. Select 2 images (Multi Select)
3. Share -> Nextcloud
4. There's already an E2E encrypted folder. I created a new folder under this encrypted folder
5. The app crashed.
6. I repeated steps 1-3 again, the new folder I created had been successfully created but when I selected it, the app crashed again.
