==> default: Checking if box 'centos/7' version '1905.1' is up to date...
==> default: Verifying vmnet devices are healthy...

either fix the settings of the VMware network device or stop the
colliding device. Your machine can't be started while VMware

Routing to the IP '172.16.109.0' should route through 'vmnet1', but
instead routes through ''.On some googling I found that
The vagrant-vmware-fusion plugin has been deprecated and is no longer maintained. Please see installation instruction here for upgrading to the vagrant-vmware-desktop plugin:

After upgrading, and ensuring that VMware Fusion is running correctly, if the error persists, please create a new issue with an updated debug output gist and I’ll be happy to have a look.
