Note1: could not test on 2019.3 due to errors: "Component could not be loaded when loading game object. Cleaning up!"
Note2: could not test on 2017.4 and 2018.4 due to Lightweight package issues
Note3: Measures that do not help:

•Deleting Library folder
•Clearing GI cache,
•Clearing baked data and Generating again
•Generating lighting via Auto-Generate
•Resetting packages to defaults
•Loading the scene with different methods (Application.LoadLevel, async loading)
