Editor crash on Play with single use of [GenerateAuthoringComponent]

Hi!

(2019.3.2f1 with Entities 0.6.0 on MacOS Catalina)

I have a simple scene with a plane and a capsule in it. On the capsule I have attached an empty struct inheriting IComponentData using [GenerateAuthoringComponent]. When I press play the editor crashes to desktop. If I remove the above component, the crash does not happen. Here is my Editor.log

I'm fairly new to unity, but it looks to me that this crash originates in Mono, even though the player settings clearly states I am using IL2CPP and not Mono as my scripting backend. I have tried switching them around and even changing between .NET standard 2.0 and .NET 4.x, but nothing seems to help. I installed the latest Mono which did not help either (although I'm not sure if Unity uses some bundled version of Mono). What more can I try?

This happened to me too on Windows and Unity 2019.3.1f1 when I was giving a workshop on DOTS. I wasn't using Asmdefs or namespaces like I usually do, and the issue doesn't affect my main work so I never looked into it.

 

For anyone else experiencing this, the bug will be solved in 0.7.0.

But it seems they didn't solve it for 2D Entities package. Version 0.22 crashes, unless using the workaround mentioned in the link
