### Bug description

The Nextcloud app consistently displays ‘No activity’ when you select an item from Explorer with sharing options. The Explorer integration (context menu) no longer responds when the item is displayed. Only a full restart of the app (killing the process via Task Manager) resolves the issue temporarily. The problem recurs repeatedly, regardless of folder size or server.

### Steps to reproduce

Nextcloud – Open the sync folder in Windows Explorer and create an external share via a link using the context menu
