AI Merge Script - how to emulate in Illustrator 2026/Mac OS Tahoe

I used to use this script ALL the time but now a forced OS and Adobe update mean it no longer works and as it’s a work computer I cannot downgrade OS etc. I have 100s of SVGs and EPS assets (how they are supplied to me) that I need in one illustrator file so we can make all colours consistent and just generally use the files in our workflow. I would like the artboards to have the name (but not the extension) of the source file being placed.

This used to take minutes with AI Merge but I cannot see a way to do it now. I can bring all the images in but pretty much have to manually rename all the artboards. I know about batch renaming but this is still very slow.

I have searched but keep getting AI “help” that is generating absolute rubbish code and does not do the job. Anyone out there got a fix or suggestion? I must be missing something, surely it’s not harder to do now?
