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

Command: ["showvminfo", "b44b246c-3b99-43a7-9eb4-772e280c1f0e", "--machinereadable"]

Stderr: VBoxManage.exe: error: The object functionality is limited
VBoxManage.exe: error: Details: code E_ACCESSDENIED (0x80070005), component MachineWrap, interface IMachine, callee IUnknown
VBoxManage.exe: error: Context: "LockMachine(a->session, LockType_Shared)" at line 3328 of file VBoxManageInfo.cpp
PS C:\jason\Metasploitable>

### Expected behavior
I'm expecting to generate two VirtualBox VMs.

### Actual behavior
I get the error pasted above.

### Reproduction information

#### Vagrant version
2.4.9

#### Host operating system
Windows 11 25H2

#### Guest operating system

#### Steps to reproduce
I've tried uninstalling and reinstalling both Vagrant and VirtualBox, rebooting after every action. To reproduce I simply type "vagrant up" and I get the failure.

Start with the supplied Vagrantfile and reproduce `vagrant up` on Windows 11, then inspect the `VBoxManage showvminfo ... --machinereadable` failure. Done means identifying a reproducible Vagrant-side cause and a focused way to verify it, or establishing that the error is external to Vagrant.
