To reproduce the issue: After importing a RC .project scene, associate a scene entity (theEnntity) to an anchor entity. Enable theEntity (isEnabled = true). theEntity renders in the scene correctly. Execute a scene reality composer behavior Notification to disable theEntity (Hide > Affected Object > theEntity). theEntity no longer renders in the scene, which is correct behavior. Then the bug occurs where you are now unable to Enable theEntity (isEnabled = true). theEntity no longer renders correctly in the scene.
