You are using a debug version of WinSCP that I have sent you based on some of your previous reports.
Go back to the official build of WinSCP.

I start the program, if I close it, a window pops up and an error log is created, which tells me a lot about how to disable it, otherwise I'm too tired to delete it.

And what about the program in general, it used to work and it was possible not to update at all, but now it's unclear what.

All the sessions have disappeared somewhere, well, my ftp connections
