### Bug description

I am having problems syncing _metadata.opf_ files from my eBooks Calibre library. After a change to my library, these specific .opf files do not sync, while everything else works fine.

The folder is on my server and accessible to Nextcloud via SMB share. On Windows, I access it using the Nextcloud folder.

I now regularly have thousands of errors in my logs every few minutes.

### Steps to reproduce

1. Existing synchronization of a folder with a Calibre library
2. Modifying your files with Calibre
3. Nextcloud Desktop synchronizes everything except metadata.opf
4. Fail again and again every few minutes

### Expected behavior

Everything synchronizes flawlessly.
