I just issued a console command from my windows pc to the device I used WinSCP and this happens.
-> shutdown -r -F +2

WinSCP 5.9.2

Error message:
Invalid access to memory.

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.
