Serial monitor extension shows blank pane

VS Code で空白の Serial Monitor ペインを再現し、次に Developer: Show Logs... を使用して Serial Monitor Logging の出力を開きます。Flathub パッケージで報告されている初期化失敗 spawn udevadm ENOENT を調査します。拡張機能が初期化され、空白のままにならず通常のモニターペインが表示されれば完了です。

Using this version of VScode, the Serial Monitor extension (ms-vscode.vscode-serial-monitor) shows a blank pane as seen below. Normally it should look like the animation shown on the marketplace.

I found these logs by Ctrl+Shift+P then "Developer: Show Logs..." then "Serial Monitor Logging".
