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

Had WinSCP open for hours just in the background. Closed my laptop lid and 10m later opened it to see this error trace. Not sure what I did or why it happened.

WinSCP 5.17.3

Error message:
Invalid access to memory.

There was a bug

I was about to send a bug report. But you not accepting no email pisses me off.

Btw you claim the email is private but below I see part of other people's email addresses.
You can probably add @gmail.com to half of these.

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

Honestly I don't know what happened... I often leave WinSCP idle after using it and during those periods I may hibernate during a switch between home and the office while making/breaking VPN connections either way.

WinSCP 5.17.9

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.
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.

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

When I first saw the message, WinSCP had been sitting idle in the background with a disconnected session (which was working fine before I disconnected the session). I first noticed the error after finished a FTP upload (to the same Web server) with a unrelated Java program. Don't know if that's significant or not. Perhaps the two FTP programs collided somehow.

Left WinSCP open when I put the machine into hibernate (which I frequently use).
When I returned to the app window, the error message was showing.

I was not doing anything when the error occurred. Sessions had been open since yesterday.
I have 2 windows with 2 sessions each running.

Started WinSCP. Went to source directory. Saw all files in that directory disappear (don't know if WinSCP did that). Then this error popped up. Never saw this error before.

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

Win10 (10.0.18363.1441) on a Dell laptop
WinSCP 5.17.10

WinSCP was left connected on an SSH session and the laptop powersaved (standby). I just resumed from standby and had this error.

This is a corp laptop and we have drive encryption, DLP, etc, so maybe it's something to do with that? Or perhaps the NIC was still down? Laptop is in a docking station, cabled connection.

First time I've ever seen an error like this with WinSCP, so, it's maybe a fluke / recent MS update issue?

Thanks

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

This error appears to have occurred with WinSCP running idle in the background. I was not actively using it when this error occurred. Note that one or more VPN connections may have been dropped and recreated as I did not detect this error immediately when it occurred. So this may be related to the dropped VPN connections.

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

No idea what what was going on when the error occurred. I only saw the error dialog only after closing several windows that were hiding it.
