These bikes are regularly overloaded. The weigh 263kg fueled and ready to ride, which means a max load of 217kg. I weigh 117kg naked, put a passenger on there of around 70kg and two heavy all-weather suits, helmets, boots, gloves, camera, tent, sleeping bags etc, etc and these things are often way overloaded.

I had a close look and it appears that all the spokes sheared?--do we know any more?

Not hugely uncommon (on any spoked wheel bike) if there are a few very loose or broken spokes in one area. I guess the rotational force of the rear wheel tear the rest apart/out.
Here’s another GSA one though to keep it BMW specific.

Spoke tension is extremely important. If you get slackness anywhere the stresses transfer to adjacent spokes possibly over stressing them. If you are planning doing any long trip get the spokes and spoke tension checked. We learned a long time back that's a maintenance item. Spokes do wear and lose tension. A wizard can do it with a tuning fork.
I did weight calcs and two up camping trips will overload most bikes.
I'm only 75 kg, but with bike gear, boots, helmet and usual pocket stuff on that's risen to 90 kilos so add 15 kilos to your naked weight before you start at all.
Solo travel with tent and the other spares and bits and pieces 25 kilos of gear isn't out of the way [10 kilo a pannier, 5 kilo top box plus tank bag?]. For me that's 115 kilos all up. Allow 10 kilos for pillions kit it's now 125 kilos. If your max is 200 kilos that's leaving scope for a 75 kilo kitted out pillion, or about 60-65 kilo naked. However if instead of 75 kilo naked weight the rider is 115 kilos that leaves you scope for a 20-25 kilo pillion.
Anyone doesn't believe me weigh up all your kit and weigh yourself in ready to ride mode,
