I can't plot the animation frame in Anylogic and receive the following error. How to solve it?

Question

I am using agent-based simulaiton and system dynamics to make the model for simulation. However, I received the following error sentences but i have no idea how to solve them.

This sentence also appears in the animation frame after simulation.

"Error while drawing animation frame. Possibly caused by dynamic properties of animation shapes. The picture will be restored when (and if) the error goes away."

I have already tried the method of adding java argument, but it still does not work. My anylogic version is 8.8.4. Does anyone have any idea? Thanks so much.

yeah, nasty error. Try to ignore ALL your animation shapes and run the model. Then, re-activate them one by one. You have a dynamic animation setting somewhere that causes this — Benjamin, Aug 09 '23 at 05:24
