connect ECONNREFUSED 127.0.0.1:18789

### Steps to reproduce

1.Install Openclaw in Windows 2022 or Windows 10 using Powershell.
2.powershell -c "irm https://openclaw.ai/install.ps1 | iex"

### Expected behavior

Gateway should remain running after installation/start.
Web GUI should load normally from http://127.0.0.1:18789/.
OpenClaw should respond normally without long delays.
Windows scheduled task should start the same working gateway process as manual foreground execution.

### Actual behavior

OpenClaw is very slow to respond when installed natively on Windows Server 2022.

The Web GUI does not reliably load from:

http://127.0.0.1:18789/
Gateway sometimes shows as installed, but the runtime is stopped.

Health checks fail with:

connect ECONNREFUSED 127.0.0.1:18789

Port test fails when the Gateway is not running:

TcpTestSucceeded : False

In some attempts, the CLI/Gateway fails with:

Failed to start CLI: Error: PlatformAdapter not registered

Manual foreground Gateway startup may work:

openclaw gateway --port 18789 --verbose

But the Gateway does not appear stable when launched through the Windows
