External exception C0000029 - @@Option@Finalize

It happened when I connected to mikrotik router (using SCP proto) and then copy one folder with some files from my desktop to root folder on that router (RouterOS 7.11)

WinSCP 6.1.1

Error message:

I know how to reproduce the problem or the problem happens frequently enough. I wish to be contacted by the WinSCP team to help resolving the problem.
