[X] I've written a clear and descriptive title for this issue, not just "Bug" or "Crash".
[X] I agree to follow Nextcloud's Code of Conduct.

Steps to reproduce

Create folder parent folder with 1300 nested folders, which in turn can contain up to 60 folders (music collection, ordered by artists/album) totaling 30GB on the server.
Log in to your server on android.
Navigate to this parent folder.
Select sync.
Sync never starts.
Navigate into the folder and select all 1300 folders (select one, then choose select all from menu)
Select sync from menu again.
Nextcloud is unresponsive for more than 2 minutes and eventually crashes.

Tested on a Galaxy S23 running android 14, kernel 5.15.94-android13-8-27763874

Expected behaviour

Nextcloud syncs the whole folder after step 4. Nextcloud does not crash after step 7.

Actual behaviour

No sync starts after step 4. Nextcloud app crashes after step 7.

Hi @MrTomato - Sorry to hear you're running into difficulties. Any chance you can capture the crash output / logs? It would be really helpful. Here's how (if crash output isn't already appearing):

https://github.com/nextcloud/android?tab=readme-ov-file#logs

Alternatively, installing a Dev build from F-Droid will give you access to logs in the app itself via Settings.

Hi @joshtrichards,

it took me a bit, but I finally managed to catch the whole mess in the logs 👍 (btw. nice tooling with the dev-app, very cool 😁)

Here's screenshots:
