Cannot install OpenSSH in Windows Server 2019

I tried to install OpenSSH by below two ways as administrator, but were both failed.

1. Install OpenSSH server by adding Windows build-in optional feature. It was able to start installing, but finally failed.

2. Install OpenSSH by PowerShell: Add-WindowsCapability -Online -Name OpenSSH.Server~~~~0.0.1.0

   Return error: Add-WindowsCapability failed. Error code = 0x80072efe

OS info (AWS server, clone from other server's image):

Edition： Windows Server 2019 Datacenter

Version：1809

OS Build: 17763.1790

Refer to some similar questions, it's suggested that to upgrade OS build. But due to some reason, it's not easy to update my server' OS build version. Is there any other solution can take a chance? Huge thanks in advance.
