vmrun error message using vagrant and vmware workstation Ubuntu 21.10

i am currently enrolled to Udacity Linux Web Server course. We are using vagrant to build out webserver using virtual box.

I do not have virtualbox install on my system. I have vmware workstation 16. I am new to vagrant.

I went to Vagrant HashiCorp Vagrant Cloud website to find ubuntu vagrant box.

i ran this command:

    krillavilla@KVOmen:~$ vagrant init express42/ubuntu12.04-chef11 \                     
  --box-version 0.1.0

This is the output I got:

    A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.

So i ran vagrant up and this what I got:

An error occurred while executing `vmrun`, a utility for controlling
VMware machines. The command and output are below:

Command: ["clone", "/home/krillavilla/.vagrant.d/boxes/express42-VAGRANTSLASH-ubuntu12.04-chef11/0.1.0/vmware_fusion/ubuntu12.04-chef11-vmware.vmx", "/home/krillavilla/.vagrant/machines/default/vmware_desktop/66de1454-1898-4090-8b52-b778fe9b555b/ubuntu12.04-chef11-vmware.vmx", "linked", {:notify=>[:stdout, :stderr]}]

Stdout: Error: The file is already in use

Stderr: 

I did some research. I tried killing the process using this command sudo pkill -f "/Applications/VMware Workstation"

That didnt work. i did some more research from these links:

An error occurred while executing vmrun, a utility for controlling VMware machines." ServiceImpl_Opener: PID ... Error: The operation was canceled (vmware_fusion provider 4.0.1 and VMWare Fusion 8) #6216

Indecipherable VMware/Vagrant error message

I am stuck and i need help figuring this out.
