OpenSSH version 8.9 inaccessibility from WinSCP 5.21

Hi Team,
                In our organization we are using OpenSSH in Windows 2019 .

We tried to upgrade OpenSSH version from 7.1 to 8.9 last week. After upgradation noticed the SFTP is inaccessible from WinSCP 5.15 So we upgraded WinSCP to latest 5.21 . Still we are NOT able to access it.
As soon as I am downgrading OpenSSH to 7.1 again , we can access SFTP from both older and newer WinSCP version.
Could you please confirm how we can upgrade our OpenSSH setup seamlessly without impacting existing SFTP clients connection


Thanks

Deepak Garg
