corona makes chaotic render URGENT HELP

hello world
im facing a big big problem. when i hit render corona renders this really messy ugly (geo) frame. what ive found out so far. it does it at every frame. i started deleting stuff and it might be from the dynamics. in standard renderer everythings fine. also when rendering an animatic everythings fine without any changes to the scene. so it must be corona that causes the issue.

I NEED HELP ASAP

thanks : )

Version of C4D, version of Corona, how are the objects made (proxies, instances, mograph), how are the dynamics made? Can you upload the scene via private uploader? Is it like this when rendering a still, or only once you are rendering a range of frames?

without the file we cant help.
