After effect crash if you duplicate a TweakShader effect present on a layer, no matter which shader is loaded.
On the other hand, if you create a second TweakShader effect and reload the same shader, everything works fine.
I am on Windows, in After Effect 25.0.1
this is a side effect of #6 , It will require removing this ill advised macro. I don't have the time to work on this right now, but I might in a few weeks. thanks for reporting this.
