### Bug description

The status bar icon is displaying a yellow exclamation mark, the tooltip reads "a problem was encountered":

At the same time, the settings dialogue for virtual file system reads "all synced":

It remains unclear if there's any problem, or what kind of problem this might be.

Access to VFS structure is possible, though performance and stability varies.

### Steps to reproduce

1. Upgrade Nextcloud desktop client to VFS edition, version 3.14.1
2. Enable VFS sync
3. Wait a while

### Expected behavior

If there is a sync problem with VFS, display information about this problem in the relevant tab of the settings window. If there is no problem with VFS sync, display a green tick as statusbar icon.

### Additional info

I'm happy to share debug logs with authorized personnel, but I don't like to see data about server names, file structure, etc. on a publicly available bug report. One entry that occurs repeatedly strikes me odd:
