Issue with SFTP sites that do not allow LIST permission (e.g. Write only)

I found a similar thread in these forums from 2018 but it didn't go anywhere.

I have an issue where I'm trying to set up an SFTP server (using Azure). I only want connecting clients to be able to upload files, but not see existing files in the directory. I am able to set the permissions accordingly to only allow WRITE privileges. LIST is unselected.

However, it seems WinSCP is having issues with this scenario. When I connect to the server, it immediately tries to do a list, and is denied leading to a nasty error dialog. However, if I dismiss the dialog, it does appear I am able to upload a file. Unfortunately after each upload, WinSCP throws this error dialog about being unable to list contents of the directory.

Is there any way to suppress this error?

I forgot to mention but I've already tried the preference to "Continue on error (advanced users)" to no effect.

You cannot prevent WinSCP from displaying the initial error.
You can prevent WinSCP from trying to reload the directory after the upload by disabling "Automatically refresh remote directory after operation":
