Network Folder wont work in V2.3.0 - V2.3.2, but in V2.2.4 Win Desktop Client

Hello, im syncing all files into a network folder. Since win desktop client v2.3.0 it wont work. When im reinstall the old version 2.2.4 it works fine. Can anyone help me? Im using owncloud 9.1.5 (after lots of updates from 8.0.9, but nothing helps).

If something stops / breaks after a version update then please always report it to the sync client developers reachable via https://github.com/owncloud/client/issues
