Invalid access to memory - Vcl::Comctrls::TTreeNode::GetTreeView

No idea what happened, WinSCP was in the background for a few days and eventually just popped up this error. The program continues to function normally as far as I can tell.

WinSCP 5.17.10

Error message:
Invalid access to memory.

<Try to describe precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.)>
I cannot think of what could cause it. Two WebDAV sessions were open. The only suspicious thing for me could be the listing of folders: more than 16000. But the listing was already loaded and I left the app idle for some time. It behaved stable while I was working with these big folders before that.

Invalid access to memory - Vcl::Comctrls::TTreeNode::GetTreeView

I was trying to reconnect to my AWS ubuntu machine after moving my laptop from one internet connection to another. This usually works smoothly and in fact did so this time too. So really, I didn't experience any problem - I just got the error message.

Invalid access to memory - Vcl::Comctrls::TTreeNode::GetTreeView

I left WinSCP running for a few days, RDPed in, used the computer for a while, then found WinSCP while Alt-Tabbing through my Windows. I have two tabs open, not including New Session. I have a workaround (restart WinSCP) so I'm only reporting because the software asked me to.

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.
