Encountered an issue with a Docker container image, preventing to destroy the vagrant environment using vagrant destroy. The error message indicated:

An action 'up' was attempted on the machine 'default',
but another process is already executing an action on the machine.
Vagrant locks each machine for access by only one process at a time.
Please wait until the other Vagrant process finishes modifying this
machine, then try again.

To resolve this issue, I used the following steps:

1. Opened the “Activity Monitor” to identify the PID (Process ID) associated with the Vagrant Docker container.
2. Executed the following command in the terminal to forcefully terminate the Vagrant process: kill -9 PID

This action allowed me to overcome the locking issue and proceed with the destruction of the Vagrant environment successfully.
