When this character appears, the behavior of the AfterEffect stops completely. This window continues to appear even when you clear it, and you eventually have to force After Effects to quit from the Task Manager.

Is there a workaround for this issue?
I don't get this window when doing anything else, but when I use trapcode particular from maxon, this window pops up and I can't use the plugin. This didn't happen until a week ago, but it's been happening since then.

It's very frustrating.
If I do it in a new project file with nothing, it runs fine, but when I create a SOLID to run particular in a project that is quite large, and run it, I get that window.

Please let me know how to solve this.

Thanks for reporting this issue, and I’m sorry you’re running into it.

Are you on macOS or Windows? Please make sure that the version of the plug-in is the latest. If the error continues, try reaching out to the Maxon support and see if they can help.

Let me know how it goes. Moving this thread from Bugs to Discussions for troubleshooting.


Thanks,
Nishu
