Resolution Note:
Hey hey!
I cannot reproduce your crash after removing the use of the deprecated, and broken method EntityManager.DestroyAndResetAllEntities() The world copying code that the sample uses does not complete successfully as it relies on destroying managed objects from within jobs that are scheduled internally (which was broken behaviour in the ECS and was deprecated as such). It is recommended to use a supported version of Entities, 1.0.x, or 1.1.x. How the project is setup currently will lead to generating indeterminate state by not resolving the many safety exceptions the current project throws when run as is.
