Can you send me an email, so I can send you back a development version of WinSCP for testing? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.

WinSCP v5.13 FAIL

Error: Exception calling "ParseUrl" with "1" argument(s): "Root folder can be specified for WebDAV protocol only

Press any key to exit...

Reverting to a specific WinSCP version and the 'Search Text' function will work.
e.g.

WinSCP v5.11.3 OK

Win10 version 1709 Build 16299.248
