Where do I find this checkbox?

After chat with AI it reports that I am missing this file:

image and it is true.

I have installed ON2 using package Manager, I have no idea why it has been ignored.

Can you send it to me via PM? Much appreciated

you type GrasshopperDevelopperSettings in Rhino, some plugins needs checked or unchecked. I just use it during debugging session.

It must be something related to either the hardware (old MBP + bootcamp) or the system (Win10).

I tried my other machine (high spec ThinkBook + Win11) and everything is fine there.

I found the problem; still Coff (grasshopperdeveloppersettings) checked, must be unchecked. I use it to debug Nautilus plugin and forgot to uncheck

It worked! Thanks.
