Unable to connect to a server using 2024.2.0: Key exchange negotiation failed

Unable to connect to a server when using SSH.NET 2024.2.0 and base64-encoded ed25519 private key. Version 2024.1.0 works fine.

This is the exception I'm getting:

Here's my code:

#r "nuget: SSH.NET, 2024.2.0"

open Renci.SshNet
open System
open System.IO

let getAuthMethod (user : string) : AuthenticationMethod =
    let key = Environment.GetEnvironmentVariable "SSH_KEY"
    let pwd = Environment.GetEnvironmentVariable "SSH_PWD"

    if not (String.IsNullOrEmpty key) then
        new PrivateKeyAuthenticationMethod(user, new PrivateKeyFile(new MemoryStream(Convert.FromBase64String key)))
    else if not (String.IsNullOrEmpty pwd) then
        new PasswordAuthenticationMethod(user, pwd)
    else
        failwith "Environment variable SSH_PWD or SSH_KEY must be defined"

let main host user (dir: string) =
    let auth = getAuthMethod user
    use client = new SftpClient(new ConnectionInfo(host, user, auth))

    client.Connect()

    let res = client.ListDirectory dir

    for item in res do
        printfn "%s" item.FullName

match fsi.CommandLineArgs |> List.ofArray with
| [ _; host; user; dir ] -> main host user dir

Start with the KeyExchangeECCurve25519 and Session entry points shown in the exception, comparing behavior between SSH.NET 2024.1.0 and 2024.2.0. Reproduce the failure using /home/vmadmin/temp/print-sftp-files.fsx with the base64-encoded ed25519 key; done when the sample connects and lists the requested directory as it did with 2024.1.0.
