Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.
Just updated from the previous version, downloaded from sourceforge. Make a full upgrade. Happens everytime I start the app.
WinSCP 5.13.5
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.
