[BUG] Files.app: Browsing "ownCloud" under "Locations" behaves erratic, impacts working of Apples "Files" app

[workflowsguy]

Steps to reproduce

1. iOS system language: german

Tapping "ownCloud" in Files.app under "Location" does not open the subfolder under "ownCloud". Nothing happens at all.
Navigating different "locations" is then mostly impossible. Only after force-quitting Files.app is browsing other locations possible again.

2. After switching iOS system language to english, browsing "ownCloud" subfolders is possible.
   However, only for some folders the containing files are shown. For others, there is a message displayed:

Content unavailable
The folder contents could not be displayed because of an unknown error.

A button Try Again is displayed, but tapping it has no effect

This behaviour also shows on iPadOS with system language "German"

Expected behavior

Files in all subfolders should be shown. ownCloud should not impact the working of the Files.app

Actual behavior

see above
