Moved ~30k remote folders to local drive (est time in the hours).
After a while, clicked 'refresh' on remote, resulted in window not responding.
Opened another instance of the same session from the taskbar jump list.
Nothing happened, so shift clicked the taskbar to open a new instance.
After an unknown length of time, a new instance appeared, partially drawn, and the original instance popped up a crash handler.

I do not know what caused this error other than the last thing I did while WinSCP was still open was to put my computer to sleep.

When I woke the computer, I saw the error message pop-up on my screen.

The error is randomly occurring while I am using the download and delete option to copy files from the sftp server to a local external hard drive.
The error pauses the downloads until it is noticed, and I click Ok.

И проблема, которую я уже неоднократно описывал, так и не ушла - после подключения по RDP приложение виснет, не открывается окно программы - оно пытается развернуться и тут же сворачивается. Это было на разных компах, сначала Win10, потом Win11, и с каждым обновлением ничего не меняется. Помогает только выключение через диспетчер.

The problem happens rarely. I cannot reproduce it.

At rdp session started copying folder over sftp. Closed rdp session (hibernated pc), when reopened session - I`ve seen that error. And error dialog about actions because of permission error.

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.

When I first opened WinSCP, everything (not just file transfer, just basic navigation like clicking "help") was extremely slow to the point of being unusable. Closing/reopening the app didn't help, and neither did restarting my computer entirely. Finally, I just left WinSCP open on my computer and disconnected it from the internet/put it in sleep mode for a few hours. When I re-opened my computer much later, I got this error.

Choosing an external drive that Windows did not recognize as properly formatted led to WinSCP freezing. Unplugging the external drive resulted in both Windows Explorer crashing and the prompt to submit an error report to WinSCP.
