iOS app craps itself when turning on auto uploading of ~35000 photos.

Steps to reproduce

1. Enter settings, Auto upload
2. Select upload from Camera roll
3. Disable "Backup new photos/videos only"
4. Set all other options to enabled.
5. Click on "Turn on auto uploading"

Expected behaviour

The app should upload all photos and videos on my iOS device

Actual behaviour

The app throws me back to the main screen and then becomes completely unresponsive.

Logs

If applicable, you can post the iOS app or server logs (removing any sensitive information).

Reasoning or why should it be changed/implemented?

App should not freeze and become completely unresponsive.

Environment data

iOS version: 18.5

Nextcloud iOS app version: 6.6.3.6

Server operating system: FreeBSD

Web server: Apache

Database: MariaDB

PHP version: 8.4.5

Nextcloud version: 31.0.5

Start in the iOS app's Settings > Auto upload flow and reproduce the failure with about 35,000 photos, using the listed steps. Done means enabling uploads no longer returns to the main screen or leaves the app unresponsive, and the photos and videos can be uploaded.
