Vagrant Up: Plötzliche Neuinstallation und alle Daten weg

Hallo Zusammen,

ich verwende Vagrant, um den Webserver lokal unter Linux laufen zu lassen nach dieser Anleitung:

https://developers.shopware.com/developers-guide/vagrant-phpstorm/

Ich nutze die Umgebung nun schon einige Wochen und hatte nie Probleme. Heute wollte ich mit „vagrant up“ wieder
Vagrant starten, doch plötzlich wurde alles neu installiert und alle Daten unter Vagrant waren weg!! Natürlich lag das System auch im Windows Verzeichnis,
aber ich habe jetzt mehrere Stunden gebraucht, um alles wieder neu aufzusetzen.

Was ist da passiert? Kann das jemand nachvollziehen? Ich will nicht nochmal von vorne anfangen.
Wie kann ich sowas verhindern?

Danke und viele Grüsse,

Jens

P.S.:

Hier ist die Ausgabe vom letzten Vagrant Start:
