It seems the inscription in the dialog-window may that one of drives has a link to file being. This can be happen if that file is not available now. On your screenshot has 'ubuntu' VM. May be the problem not associated with vagrant VM ?
In picture of last post I set a status your needed at 'Settings - Storage'. with that Vagrant works fine.
Having reproduce bug by the wrong link at textbox.
Set are bootable drive is are 'hard drive' to VM nes.
Try to remove all no-hard drives from all VM and to cleared them textboxes of any file links inside.Describe the result.
