Updating Model Reference Sim Target

Hello

I am using model referencing and sometimes the model gets stuck at "Updating Model Reference Sim Target". See below snapshot.

Sometimes the Simulation works and sometimes its just gets stuck.

I update the models before running averytime.

The model has been attached.
