I've tested the plugin in a brand new project and wasn't able to replicate the crash. I'm wondering if the issue might be due to the plugin parameters needing to be reinitialized. To troubleshoot further, could you please try reinstalling the plugin in a new project and see if the issue persists? If you're still experiencing the crash, I'd appreciate a zip file of the project that reproduces the issue, which you can email to support@dmplugins.com. This will help me investigate and resolve the problem more efficiently.
