Vagrant setup error: There was an error while executing `VBoxManage`, a CLI used by Vagrant for controlling VirtualBox

Question

i am new to coding and am currently facing an annoying issue when installing Vagrant and it is stopping from completing my studies, i am using:

macOS Big Sur 11.3.1 on a MacPro

I've tried uninstalling / installing both Vagrant and Virtualbox using their own websites and using brew, but no luck so far to solve the below issue.

vagrant --version
Vagrant 2.2.16

Here is log from my terminal (also tried using iTerm but the same issue):

vagrant up

There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: ["startvm", "1c862e17-0e9e-475d-8b1c-7df81fc3b144", "--type", "headless"]

Stderr: VBoxManage: error: The virtual machine 'vagrant_default_1621523735226_48464' has terminated unexpectedly during startup with exit code 1 (0x1)
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component MachineWrap, interface IMachine

Screenshot

I trying to vagrant up this file from my course materials, and i just download it and change the directory with "cd" to the folder with the vagrant file then to vagrant up.

Thank you so much,

UPDATE:

I tired the some of the solutions here but it didn't work too, and when i tried the below code i got a lot of error messages.

sudo "/Library/Application Support/VirtualBox/LaunchDaemons/VirtualBoxStartup.sh" restart

sudo "/Library/Application Support/VirtualBox/LaunchDaemons/VirtualBoxStartup.sh" restart
