SessionOptions.SshHostKeyFingerprint cannot be set, when the protocol is FTP.

That's your error, it does not say anything to us.

Please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate the session log file, set Session.SessionLogPath. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

The windows does not close after entering the log to sessionlog.log (file)
I'm not sure I understand.
The program/window does not close, as you have an infinite loop there:
while($True)
