Vagrant very slow on Windows 11

Hi there folks,

I’m using a newly-installed Vagrant with VirtualBox on Windows 11 - specifically, I’m playing with setting up VS Code with an Ubuntu guest instead of using WSL. Vagrant is super slow, though:

C:\Users\adam> Measure-Command { vagrant version }

Days              : 0
Hours             : 0
Minutes           : 1
Seconds           : 22
Milliseconds      : 226
Ticks             : 822262010
TotalDays         : 0.000951692141203704
TotalHours        : 0.0228406113888889
TotalMinutes      : 1.37043668333333
TotalSeconds      : 82.226201
TotalMilliseconds : 82226.201

This is running on pwsh 7.2.2:

C:\Users\adam> $PSVersionTable

Can anyone help me diagnose?
