Hi @clippy-0099,
Thanks for sharing this. I understand how concerning it is to see such high memory usage. To clarify, AIRobin is a background component used by Illustrator for Background Save and Background Export, which is why it can run even when you're not actively using AI features. You can read more about it here:

As a first step, please completely close Illustrator and restart your machine, then check if the memory usage comes down. If it doesn't, try manually resetting Illustrator preferences using the steps here: https://adobe.ly/3N7To3P. You can also follow this short video for a manual reset:

If the issue still persists, please try removing Illustrator using the Creative Cloud Cleaner Tool and then reinstalling it via the Creative Cloud desktop app:

Please let me know how it goes after you've tested these steps.
