Strange sparkles from either material or lighting

[wmonprode]

Hello!

I am a student working on my project and am running into some issues with a material or lighting aspect. On the yellow half of my project, I am getting some form of sparkles that reflect everywhere. I've tried different materials on the yellow but they still remain. Everything inside the enclosures is the same material which is the confusing part since it isn't occurring on the green side. As someone that is quite new to this, I've messed with my materials and lighting settings to no avail. It was still occurring with CPU rendering and GPU leaving me out of ideas. Any other tips to improve my render would also be appreciated. I've attached the package and image below (unsure how to place the image in text).

Thanks in advance!
