The problem happens rarely. I cannot reproduce it.

I have dragged some folders from local machine (directly from windows explorer to remote client folder view), meanwhile, I have copied a large text (specifically, AdminLTE 3.0.5 https://github.com/ColorlibHQ/AdminLTE/releases -> pages/charts/flot.html), then I right clicked on WinSCP remote folder view pane (in intention to create a new file), That's when I got this error.

The problem happens rarely. I cannot reproduce it.

Tried to create new folder on remote ssh site.
When having large clipboard e.g. copied content of one html file (few kbs) the winscp crashes. When I have clipboard content about 1 byte suddenly works fine. Always crashes with "full" clipboard.

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.

<Try to describe precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.)>
<If relevant, consider attaching a session log file or a screenshot)>

WinSCP 5.15
