2019.1.3 Exception: Package file ... already has a USES declaration!

Trying to build after upgrading a project from 2019.1.1 to 2019.1.3 and getting:

Exception: Package file D:\HDI_PROJECTS\2019\UnityProjects\MagicLeapParticleHands\com.hdinteractive.mlhello.package already has a USES declaration!

Anyone else run into this? Here is the full error:

Yes, I have the same error and also with Lumin. I guess we should go to Magic Leap with this?

 

Ok, so Magic Leap says:

Delete the com.company.productname.package file, which is in the folder above your Assets folder in your project.

 

Ah, nice and easy.
