"Explode Block" in Human not working in Rhino 8

Hello,
It seems “Explode Blocks” component doesn’t work in Rhino 8. I am using the same script in both Rhino 7 and 8. As you can see in snips below, it works in Rhino 7 but gives me an error in Rhino 8 (Solution exception:Object reference not set to an instance of an object.)
Anybody knows what I should do?
Thanks!


It’s been a while since I posted this, and I haven’t received any responses yet. I’d really appreciate any insights or thoughts—does anyone have experience with this?
