I wonder if it’s possible that there’s something different about the antenna on a 2021 compared to prior years. Seems unlikely, but maybe there was a change in their sourcing.

I don't have a definitive answer. I looked it up and SiriusXM is only in the US, Canada and Puerto Rico. I also looked back through my pictures from when I was in the Middle East (pics of 100's of 200 series) and don't see any shark fin antennae. That isn't an answer, but it leads me to believe it is not a ROW thing, but maybe some our international members can chime in?
Here's an overhead shot of a newish vx-r:

I have a 2016 and I will bet they are the same at least from the 2016's onward. My Gobi rack was specific to the 2016 and has a "cut out" of sorts for the fin. So others were aware and worked around it. I was looking at other rack options last night and at least one other one (may have been Prinsu or Front Runner seems to have a cutout or something that avoided a conflict with the fin. So other makers accommodated the fin without simply increasing the height of the rack.
I currently have a Frontrunner on my 2019...no cutout for the shark fin as the side rails place the rack above it.
You're right of course. I also checked the Front Runners again and no notch. I was probably just imagining. Dreaming. Wishful thinking.

My Gobi stealth has a cut out as well for my 2015.
Mainline Overland just confirmed thru ARB that there's a fitment issue due to the antenna. ARB has halted all rack shipments until they have a resolution. I've requested an ETA on that resolution. . .

Ok, so we called ARB today and get this, they said oh yes, we have a fit issue. ARB is developing a different fit kit etc. blah blah blah but that does not help me now. I guess we will have to custom fab some spacers to bring it up a little higher. WTH! Photo shows we took the shark fin off to see how much space we need, and it is about 3/4"
Looks like the 4Running crew has seen this issue: Toyota-4Runner.org - https://www.toyota-4runner.org/5th-gen-t4rs/215885-low-profile-xm-shark-fin-antenna-swap-3.html

The shark fin has the SOS telematics in it. So we really cannot modify it.
ARB certainly needs to offer a taller mounting kit for US spec Cruisers, but a spacer could be placed between the mounting brackets and the rack in order to create the needed clearance. This is not ideal but it would allow use of the rack until ARB steps up with a solution.
Which is why no really low profile racks exist for the 200 probably. . .
Go fast campers has a shark fin delete kit for the 4Runner, maybe learn from how they approached it?

Any solutions to this yet? I'm hoping it was just a fitment issue overlooked by the installer?
ARB has confirmed the issue and they've stopped US shipment of the racks until they have a solution (this is according to Mainline Overland through whom I have a rack on order). I'll update this thread when I get more information.
