I have found why INI files with personal config saved in my documents not work.
In question Windows 10 Ransomware Protection !! will be activated in my professional computer.
This option is activated by my company by error last week.

So disable this option or parameter well WinScp and putty allow app.
Resolved for me.

Thanks for sharing your findings.
WinSCP should have produced a better error message anyway.
So I have at least improved that:
