Brief description of your issue

When starting a PowerShell session without an active internet connection, the Microsoft.WinGet.CommandNotFound module fails during its background WarmUp() task. The resulting CatalogConnectException is unhandled and causes the entire PowerShell process to crash with exit code 0xe0434352 (process exited with code 3762504530).

Steps to reproduce

1. Disconnect the PC from the internet (turn off Wi-Fi / unplug Ethernet).
2. Open a new PowerShell / Windows Terminal session with Microsoft.WinGet.CommandNotFound enabled.
3. Observe the startup error and process crash.

Expected behavior

Background catalog warmup failures due to lack of network connectivity should be handled gracefully (e.g., swallowed or logged silently) without crashing the PowerShell host process.

Actual behavior

An unhandled System.Management.Automation.CmdletInvocationException wrapping a Microsoft.WinGet.Client.Engine.Exceptions.CatalogConnectException is thrown from WinGetCommandNotFoundFeedbackPredictor.WarmUp(), terminating the PowerShell session immediately.
