Railsが起動しなくなってしまいました

rails -serverが起動しなくなってしまいました。

windows10でVirtualBoxでubuntu上でrailsを構築しています。
先日のwindows10アップデートで勝手に再起動されて、ubuntsは強制的に落とされてしまったのが原因だと思うのですがよくわかりません。

db/test.sqlite3が強制終了でファイルロックされてしまったのかと思ってこのファイルをコピーして、元のtest.sqlite3を削除し、コピーしたファイルをtest.sqlite3にしてみたのですがダメでした。

以下が実行時の結果です。
何か対処法がわかりましたらどうぞよろしくお願い致します。

環境：
Ruby On Rails 5.1
windows10上でVirtualBoxでubuntu17.04

user@ubuntu1704:/media/project/test_project$ rails -s
