Multiple Issues

[ColossalMonk]

I am facing multiple issues with things as 'Input System', 'AR Human Body Manager','AR Reference Point Manager', 'AR Occlusion Manager', 'XR CPU Image', 'AR Human Bodies Changed Event Args', 'Configuration Chooser', 'Configuration Descriptor', 'Feature', 'Configuration', 'XR Human Body Pose 2D Joint', 'AR Human Body', 'Camera Facing Direction'. I googled it and read the documentation and found that these error occurs due to use of different version of AR-Foundation, AR-Core XR Plugin, AR-Kit XR Plugin, AR-Kit Face Tracking , also you are using preview packages for the above 4, so it's my humble request that please let me know the exact version that you are using, and lastly I am using Unity 2020.1.
