Hi everyone, I’m having this error and don’t know how to solve it. Please help me with the solution. Thank you very much. My English is not very good.

Seeing your name, I first thought maybe it could be a language/non-UTF8/special character problem that causes a problem.

But as I see, your Rhino looks like running in English.

Do you use special characters in file names, paths or in the file ?

I don’t think so, I use all English

The only issue i can see is possibly conflicts with other plugins. Can you try turning them on/off?

Eg, in your earlier screenshot I saw D5 LiveSync in there too - not sure which one of them could be the culprit, but it’s an option.

do you think it’s because my rhino version is old

This is the notification code

This is likely the problem.
The minimum version of Rhino8 our plugin will load with is 8.9 as you see in your screenshot.
So I recommend updating to something newer.

I remember the first few versions of Rhino do not properly giving error messages for plugins that fail to load. So this also explains why you’re seeing so little information about the failure.
