Not working with Microsoft.OpenSSH.Beta

[padinko]

I have problem using npm with ssh package from gitlab
I found newer version of microsoft ssh implementation can help, so i tried it
i installed it with command

winget install --id=Microsoft.OpenSSH.Beta

versions i use on windows 11:
(system) OpenSSH_for_Windows_8.6p1, LibreSSL 3.4.3
(beta) OpenSSH_for_Windows_9.5p1, LibreSSL 3.8.2

when i start nCryptAgent and use it with system ssh, it works well when connecting to servers, but npm install fail with: unexpected disconnect while reading sideband packet
then when i swith to ssh beta, ssh connection works every second time.. every another second time i got Permission denied (publickey)
then i restarted nCryptAgent and ssh connection is not working at all.

i tried verbose ssh -vvvT HOST and this is probably problem:

debug3: ssh_get_authentication_socket_path: path '\\\\.\\pipe\\openssh-ssh-agent'
debug2: get_agent_identities: ssh_agent_bind_hostkey: invalid format
debug1: get_agent_identities: ssh_fetch_identitylist: agent contains no identities

i need to restart nCryptAgent again after uninstalling beta ssh

It is hard to understand from your description which part is at fault and how npm is relevant here. If you claim the problem is the use of nCryptAgent with Microsoft.OpenSSH.Beta, provide a minimal example that can reproduce it.
