uniyt+MRTK报告一堆conflicts with解决办法

unity打开报错,包括不限于:Library\PackageCache\com.microsoft.mixedreality.toolkit.foundation@f2323a9b7aec\SDK\Experimental\NonNativeKeyboard\Scripts\CapsLockHighlight.cs(24,17): error CS0246: The type or namespace name ‘NonNativeKeyboard’ could not be found (are you missing a using directive or an assembly reference?)
