Installtaion von Erweiterung - Unable to write config file - GELÖST

[Molson_Ice]

Hallo! Ich habe diese Woche angefangen mit Contao zu arbeiten. Die Installation lief fast reibungslos. Contao Version 4.8.5
(04.11.2019, 17:14) mit Laragon. Den Contao Manager kann ich aufrufen. Nur wenn ich jetzt versuche eine Erweiterung zu installieren bricht der Konsolentask mit folgender Meldung ab.
Hat jemand eine Idee?

### Der Hintergrundprozess wurde unerwartet beendet ###

Die Lösung:
Ich habe den Contao Manager nochmals per Composer in das Verzeichnis web geladen, danach hat auch das Installieren der Erweiterungen funktioniert.

curl https://download.contao.org/contao-manager/stable/contao-manager.phar -o contao-manager.phar.php
