Possibly a duplicate of #1556? If so, try @bagajjal 's private ssh-shellhost.exe binary from there and report back. Or upgrade to a newer operating system with ConPTY support.

Does this problem still exist on Windows 10/Server 1903 or newer with KB5003173 installed (which upgraded the OpenSSH version in Windows Features to 8.1 this week)? If not, can you close this ticket?

Thanks @mgkuhn . Duplicate of #1556. The fix will be part of next release, Openssh V8.6
