Cannot uninstall ai render extension from older version

Hi,

I downloaded the ai render rbz file from the extension warehouse without realizing that it isn’t designed for my version, SketchUp 2021 Pro, which I use for my professional work. I went through Extension Manager to install and received the error that it required SketchUp 2024 or higher. I tried to find it through my 2021 Extension Warehouse to uninstall but couldn’t locate the file. I searched through the 2021 plug-ins folder and also could not find the file. I’d like to uninstall it.

I teach SketchUp to students and have other current Student versions on my computer but I did not install through them.

Now every time I start SketchUp 2021, it gives me the error message. I’m attaching screenshots. Perhaps I’m missing it in my list. Thank you for your time.

This one, DIffusion. Old name.

Thanks!
