Investigate if the function dispatcher state is getting properly reset

Investigate if the function dispatcher state is getting properly reset; there is potentially a bug here and we should look into which potential scenarios/conditions are happening where we do not reset the state (i.e. restart use case)

Start by tracing the function dispatcher state and its reset paths, focusing on the restart use case and other conditions where state may persist. Done means the relevant scenarios are identified and the dispatcher’s reset behavior is verified or a specific bug is reproduced.
