I'm going through the tutorial app and I have reached this step:
https://portal.liferay.dev/docs/7-0/tutorials/-/knowledge_base/t/defining-the-component-metadata-properties

I was having issues with the bundle appearing in the widget menu so I thought I would uninstall it and re-install it to see if that resolved my issue. However, now when I try to install the bundle I get an exception with the message 'The bundle has been uninstalled '.
This isn't entirely helpful as I know I uninstalled the bundle, I am wishing to install it again and I can't. Does anyone know why?

Thanks,

EDIT: upon starting the Liferay server I get the following exception:
