OpenSSH version 8.9 inaccessibility from WinSCP 5.21

[rapier]

Hey there,

I was able to connect to OpenSSH 9.0 with WinSCP 5.21.1
I'd give that a shot - the release notes state that the 5.21.1 release 
upgrades the TLS/SSL core to 1.1.1p. There may have also been an issue 
with the public key negotiation. I saw that with WinSCP 5.14 which is 
from 2013 so that's not all that surprising.
