### Bug description

On the 3.14-macOS-vfs clients that we are using, we often see the exclamation mark icon on the status bar. Hovering on it, it says the vfs sync had an issue.
However, opening the settings panel and clicking on "Create debug archive" freezes the UI and the Nextcloud process becomes unresponsive. This seems to be related (kind of a side effect) to the sync issue itself, because when the sync status is OK, it's possible to generate the debug archive without freezes.

The problem is, I have no clue on what the problem is and therefore haven't found a way to prevent/work around it.
...

### Steps to reproduce

1. Have the client running for at least some hours.
2. The client shows an exclamation mark on the status bar, complaining the last sync had an issue.
3. Open the settings panel and click on "Create debug archive"
...

### Expected behavior

The debug archive should be created.
Observed behaviour: the panel hangs and the process becomes unresponsive, I have to kill it.
Seems similar to what happened a few versions back, on opening the settings panel, where the process froze and needed to be killed.
