Can't Browse UNC Path in network drive

We are trying to open UNC path to open network folder using WinSCP 5.19.6 and 5.21.1 installed on Win 11.

From the left pane of WinSCP, when trying to browse UNC Path in network drive, nothing happen.

Our issue is similar to Can't Browse C:\Users\User\ appdata but we are trying to browse network drive, and the file is not hidden and the user have full control permission.

Thanks.

How exactly are you doing that? Can you post few screenshots (from the latest version of WinSCP) documenting the problem?
