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

I was connected from my Windows 10 machine to a Sun Solaris 5.10 machine on a nearby, associated network. I have been using WinSCP to connect to our Unix systems for almost a decade, and have never seen this before.

WinSCP was open but not in use. When I switched to the application window, I saw the error message.

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

This error pops up at seemingly random times, typically when signing back into my session at the beginning of the work day, after I had been logged in remotely (using Remote Desktop) from home. The server to which I had been connected was also connected via a Putty session, and that session did not close (due to any type of networking/connection timeout) so I don't suspect that would have been the cause of this issue.

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

The WinSCP program was running, but I was not interacting with it. The computer went to sleep (at lunch time) while some other connections to a Linux computer were still running. After returning, WinSCP had had an Invalid Memory access with and Putty and VNC console also lost their TCP/IP communications connection (the last 2 are common at lunch time).

This happened after resuming my Windows 10 laptop from the hibernate state, so, may be related to that. I am only reporting this since WinSCP seemed to encourage that.

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

Lenovo Thinkpad T470 Windows 10 Pro x64 version 10.0.18362 Build 18362.

I used WinSCP to upload some files, then left the session running in the background while doing other work, then put the laptop into hibernate mode. As usual for this machine, it then went through (presumably) multiple cycles of spontaneous wake, sleep and/or hibernation states until its next use. For most of this time, the machine was out of range of any known networks. I woke it from low-power-induced hibernation to find this error message.

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

WinSCP had been up and running great for a few days, connected to a few different BeagleBones running Debian 9. Then first thing this morning I noticed this error. It popped up sometime during the idle hours.

WinSCP 5.15.4

Error message:
Invalid access to memory.

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

I was ssh connected to the device and then disconnect by going (laptop) to sleep.
Next time I start the laptop (still not connected to the device) an error occured.
