Thanks for the report!

Just a heads up: I believe ECS is only supported in Unity 2020 https://forum.unity.com/threads/experimental-entities-0-50-is-available.1253394/

My pleasure! Actually with the recent release of Entities 0.51 it’s supported on Unity 2021.3.4f1+! https://forum.unity.com/threads/experimental-entities-0-51-is-available.1281233/#post-8232024
