Need help with Illustrator lagging after isolating groups

I recently upgraded my work Mac from iMac Pro (2017) to a Mac Studio (2022) and I notice a few quirky differences. Most are minor but this one really interrupts my workflow because of the lag (or delay) it causes. I want to see if anyone knows what is causing it so that I can stop interrupting myself when I work!

Ok, so the issue is when I want to edit something within a group. Typically I isolate the selected group so that it's easier to select the items I need to. Well, on the new Mac, Illustrator does this: https://youtu.be/kKAssq74X7E. This is just a sample document to show as I can't show our customer's artwork, but as you can see, even with simple shapes there is a noticeable lag after isolating the group.

I am working locally, no network issues should cause this. I have tried switching from GPU to CPU and that does seem to eliminate the problem, but everything else is slow to work with. So that's not a feasible option for me either. I have uninstalled and reinstalled Illustrator as well and no improvement. I don't really know what else to try! I am really leaning towards it being a computer problem rather than Illustrator but theoretically this Mac should be way faster than my old iMac. Just to be thorough, here is the info on both computers:

iMac Pro (2017)

Mac Studio (2022)

Does anyone have any ideas on how to remove this lag (if possible)?
