We are experiencing a critical issue following a Nextcloud upgrade.

### Issue description:

- Uploading **single files works correctly**

- Uploading **folders via drag & drop fails**

- Error message: _“The target folder no longer exists”_

- From browser developer tools:

- Behavior observed:

### Additional details:

- Upload works when dropping into the **root directory**

- The issue only occurs when uploading into a **subfolder**

### Environment:

- Nextcloud version: **33.0.0** (previously 32.x)

- Storage: **CIFS network share (NAS)**

- Datadirectory is located on this mounted share

### Permissions:

We have verified that:

- The web server user ( **www-data** ) has full read/write permissions on the storage

- Manual file and folder creation from the server works without any issue

Request:

Could you please advise:

- If this issue is known with WebDAV and/or CIFS storage

- If there is any recommended configuration or fix

- Or if this could be related to caching or permission handling

This issue is impacting production usage, so your prompt assistance would be greatly appreciated.
