WinSCP error code 3 after clicking on /. How to fix?

Question

FTP

Hosting - BlueHost. FTP client - WinSCP.
The folder structure has the following tree:

When clicking on "/" error 3 appears (not surprisingly, I do not have access to this folder, but for some reason you can poke at it, although it should not exist at all). And that's it, you need to restart the server. The worst thing is if there is a checkmark "remember the last folder" in the account settings. In this case, "/" is generally written to the last folder and immediately gives "error 3" when entering. It is necessary to change the account settings, and prescribe the correct let to (your) FTP. But this is unhealthy nonsense. Since any misclick on this folder in the tree forces a reconnect operation to be performed at least.
