I get this error when my “main menu” scene is loaded, which does not use ECS. The scene with ECS is loaded later on. No idea what could be causing this. Any suggestions?

You need to build with special platform plugin instead of default Build / Build and Run.
Since data required for conversion is missing without it.
https://docs.unity3d.com/Packages/com.unity.entities@0.17/manual/install_setup.html

Automatic bootstrap occurs on application load, so it doesn’t matter what scene order is.
