I have a multi-tab WinSCP session active all the time. I leave it "running" even when I am not using it for long periods of time, so it lasts through many daily *hibernations* of Windows (11), in this case it was at least two weeks. The only unusual aspect of this issue is that it occurred (well) after Windows started bugging me about restarting in order to set some pending Windows updates. I still hadn't done the updating when this happened. I think it's just a one-hit wonder.

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.

WinSCP connected to a host through a VPN.
During the night the VPN drops, and in the morning I get (quite regularly) this error.

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.

Left a long-running transfer overnight and came back to this; I have done a similar process many times before and this is the first time I've seen this crash.
