Resolution Note:
This isn't related to the DOTS Editor package as the project does not contain the package. If it is related to the Entity Debugger, the package being tested is "com.unity.entities": "0.11.1-preview.4". As we do not support previous versions of the Entities package, I suggest to the user that they upgrade their Entities package and their DOTS project.
There are known performance issues with the Entity Debugger and some have even been fixed in the later versions of the Entities package. The Entity Debugger will be deprecated soon as well.
