Invalid access to memory - _pfd_close

I just tried to reconnect to a session that goes through an SSH tunnel (after a few hours of the computer being in hibernation). This happened (I think) after giving my credentials for both.

Good luck :)

WinSCP 5.9.3

Error message:

The problem happens rarely. I cannot reproduce it.
