For those who might be encountering this issue with recent changes to your computer involving Hyper-V, you'll need to disable it while using VMWare or VirtualBox. They don't work together. Windows Sandbox and WSL 2 need the Hyper-V Hypervisor on, which currently breaks VMWare. Basically, you'll need to run the following commands to enable/disable Hyper-V services on next reboot.

To disable Hyper-V and get VMWare working, in PowerShell as Admin:

bcdedit /set hypervisorlaunchtype off

To re-enable Hyper-V and break VMWare for now, in PowerShell as Admin:

bcdedit /set hypervisorlaunchtype auto

You'll need to reboot after that. I've written a PowerShell script that will toggle this for you and confirm it with dialog boxes. It even self-elevates to Administrator using this technique so that you can just right click and run the script to quickly change your Hyper-V mode. It could easily be modified to reboot for you as well, but I personally didn't want that to happen. Save this as hypervisor.ps1 and make sure you've run Set-ExecutionPolicy RemoteSigned so that you can run PowerShell scripts.

# Get the ID and security principal of the current user account
$myWindowsID = [System.Security.Principal.WindowsIdentity]::GetCurrent();
$myWindowsPrincipal = New-Object System.Security.Principal.WindowsPrincipal($myWindowsID);

# Get the security principal for the administrator role
$adminRole = [System.Security.Principal.WindowsBuiltInRole]::Administrator;

# Check to see if we are currently running as an administrator
if ($myWindowsPrincipal.IsInRole($adminRole))
{
    # We are running as an administrator, so change the title and background colour to indicate this
    $Host.UI.RawUI.WindowTitle = $myInvocation.MyCommand.Definition + "(Elevated)";
    $Host.UI.RawUI.BackgroundColor = "DarkBlue";
    Clear-Host;
}
else {
    # We are not running as an administrator, so relaunch as administrator

    # Create a new process object that starts PowerShell
    $newProcess = New-Object System.Diagnostics.ProcessStartInfo "PowerShell";

    # Specify the current script path and name as a parameter with added scope and support for scripts with spaces in it's path
    $newProcess.Arguments = "-windowstyle hidden & '" + $script:MyInvocation.MyCommand.Path + "'"

    # Indicate that the process should be elevated
    $newProcess.Verb = "runas";

    # Start the new process
    [System.Diagnostics.Process]::Start($newProcess);

    # Exit from the current, unelevated, process
    Exit;
}
