Theme Updater bricht ab: RuntimeException System::importStatic() failed

[D@TK]

Hallo zusammen,
ich möchte eine Contao 4.9 Kunden-Installation hochziehen und mittels Theme Updater (Lizenz ist eingekauft) die enthaltene Eclipse X Installation (3.0.19) updaten!

Dazu habe ich Schritt für Schritt diese Punkte abgearbeitet:
https://www.premium-contao-themes.co...dater-pro.html

Ab Punkt 3 bricht die Installation ab (2 Versuche sind durch):

1. Contao 4.4 auf min. 4.13 LTS updaten check
2. Theme-Updater installieren & starten check
3. Migrationsroutinen führen automatisch manuelle Änderungen durch Abbruch mit Fehler

Die Fehler aus dem Logfile sind hier:

Die Stelle wo die Fehlermeldung erscheint:

Woran kann das liegen? Ich bin für Eure Tipps dankbar.

Das sind sehr alte Versionen!
https://service.premium-contao-theme...-auf-4-13.html

Angenommen der TU hat geschafft die aktuellen Module zu koperen, dann ist er am leeren des Caches gescheitert. Du kannst versuchen einmal den Symfony-Cache manuell zu leeren: var/cache leeren via FTP.

Andernfalls den Leitfaden oben befolgen.

ps. Das ist eine externe Erweiterung, deren Kompatibilität natürlich ebenfalls sichergestellt werden muss.
