Nunit Error when installing Meta interaction sdk as part of All-in-One

Have been trying to install the v60 of the meta All-in-One SDK to get the meta movement pack to update. Seems like no matter what fixes I try I always get an error as follows:

Library\PackageCache\com.meta.xr.sdk.interaction@60.0.0\Editor\Utils\PluginUpdater.cs(28,16): error CS0246: The type or namespace name 'NUnit' could not be found (are you missing a using directive or an assembly reference?)

Library\PackageCache\com.meta.xr.sdk.core@60.0.0\Editor\BuildingBlocks\BlockBaseData.cs(26,7): error CS0246: The type or namespace name 'NUnit' could not be found (are you missing a using directive or an assembly reference?)

Library\PackageCache\com.meta.xr.sdk.core@60.0.0\Editor\BuildingBlocks\BlockData.cs(24,7): error CS0246: The type or namespace name 'NUnit' could not be found (are you missing a using directive or an assembly reference?)

Library\PackageCache\com.meta.xr.sdk.core@60.0.0\Editor\BuildingBlocks\BlockDownloaderData.cs(23,7): error CS0246: The type or namespace name 'NUnit' could not be found (are you missing a using directive or an assembly reference?)

I followed the steps to migrate from the Oculus Interaction SDK here:

https://developer.oculus.com/documentation/unity/unity-package-manager/#migrate-from-oculus-integration-sdk

but it still gives me errors.

These errors were not present before using the new sdk
