Invalid access to memory - TCustomScpExplorerForm::DoSynchronize

The computer I was syncing was powered up, however it was connected to a PoE Ethernet switch that had been powered off, so just the Ethernet connection was down. When I powered up the PoE switch and attempted to reconnect without stopping WinSCP (I had it set to "keep the remote files up-to-date"), it crashed.

Re: Accès mémoire invalide - TCustomScpExplorerForm::DoSynchronize

Thanks for your report.
This is probably fixed already:

Accès mémoire invalide - TCustomScpExplorerForm::DoSynchronize

when "keep the distant updated" is activated, the detection of a change crashes the process of watching, before uploading a new file.
when i click ok on the error box, it returns to the "keep distant updated" then i can click ok to run it again.

The error happens since 5.16 (beta)

I saved a HTML file in Visual Studio Code when the error occured.

Invalid access to memory - TCustomScpExplorerForm::DoSynchronize

I don't really have any additional information. I run WinSCP to sync a remote folder and it starts up when I fire up the machine then runs minimised (to system tray). It normally runs all day without issue and this is the first time I have seen the error. On this occasion it popped up the login screen after running for about 5hrs, I selected login and got the error. Closing WinSCP and starting it up again worked without issue. Nothing else obvious occurred.
