To resolve error "Could not agree host key algorithm" while scripting PowerShell using .NET assembly

Hi, Greetings!!!

I am new to PowerShell scripting and WinSCP as well. My scenario is to compare timestamp off two files from two different directories from WinSCP. Hence I started first making connection with server using PowerShell which is generated by .NET assembly of WinSCP using below code.

WinSCP version is 6.3.1

However, I am getting below error
Error : Exception calling "Open" with "1" arguments(s): " Could not agree host key algorithm" (available: rsa-sha2-XXX,rsa-sha2-256)
try
{
    # Load WinSCP .NET assembly
    Add-Type -Path "WinSCPnet.dll"
 
    # Setup session options
    $sessionOptions = New-Object WinSCP.SessionOptions -Property @{
        Protocol = [WinSCP.Protocol]::Sftp
        HostName = "example.com"
        UserName = "user"
        Password = "mypassword"
        SshHostKeyFingerprint = "ssh-rsa 2048 xxxxxxxxxxx..."
    }
 
    $session = New-Object WinSCP.Session
 
    try
    {
        # Connect
        $session.Open($sessionOptions)
 
        # code for comparing timestamp
       
    }
    finally
    {
        # Disconnect, clean up
        $session.Dispose()
    }
 
    exit 0
}
catch
{
    Write-Host "Error: $($_.Exception.Message)"
    exit 1
}
Kindly help me in resolving this error.

Can you connect in WinSCP GUI? Please post logs both from the GUI and the .NET assembly.
