Replace lines 483-491 in Add-AppDevPackage.ps1 with below script and try again:

if ($DependencyPackages.FullName.Count -gt 0)
{
    Write-Host $UiStrings.DependenciesFound
    $DependencyPackages.FullName
    

    # Install dependencies one by one first
    foreach ($dep in $DependencyPackages.FullName) {
        echo "Installing dependency: $dep"
        try {
            Add-AppxPackage -Path $dep -ForceApplicationShutdown
            echo "Successfully installed: $dep"
        } catch {
            echo "Failed to install dependency: $dep - $($_.Exception.Message)"
        }
    }
    
    # Now install the main package
    echo "Installing main package: $($DeveloperPackagePath.FullName)"
    Add-AppxPackage -Path $DeveloperPackagePath.FullName -ForceApplicationShutdown
}
