Tried removing Source, delay and SelectOutput5 - no difference.
Solution
There are a few blocks in AnyLogic that cannot work without corresponding animation objects. Conveyors are one of them.
See example below you need to draw a path and then select the path in the conveyor setup for the conveyor to work
There are currently two types of conveyor blocks in AyLogic, the one in the Process Modeling Library and the one in the Material Handling LIbrary. You used the former, I would recommend the latter. Check some of the documentation here.
