更新してvagrant upしなおしたら下記エラー
———
Vagrant failed to initialize at a very early stage:

The plugins failed to initialize correctly. This may be due to manual
modifications made within the Vagrant home directory. Vagrant can
attempt to automatically correct this issue by running:

vagrant plugin repair

If Vagrant was recently updated, this error may be due to incompatible
versions of dependencies. To fix this problem please remove and re-install
all plugins. Vagrant can attempt to do this automatically by running:

vagrant plugin expunge –reinstall

Or you may want to try updating the installed plugins to their latest
versions:

vagrant plugin update

Error message given during initialization: Unable to resolve dependency: user re
quested ‘vagrant-hostsupdater (> 0)’

コマンドプロンプトで下記を行ってから再度vagrant upしたらvagrantが立ち上がってアクセスできました
