Both of those links have good info I've not seen before.

I think you've misunderstood though. I got a usable Robe by NOT simming and then exporting the zeroed pose.  I wasn't getting exploding just an odd unexplained wind like force as mentioned.

I'd be curious if that happens with you using the default pose of a G8 or G8.1. I stay current on software, but some months back there were issues with Daz 4.21. Fortunately, I had the previous on my laptop & used that for several weeks. The issues got resolved when there was a update to the Gen9 essentials. I don't use Gen9 but apparently that will affect other things. There was another Gen9 Essentials update recently, so I'm a bit gunshy.

On my to-do list though is to learn Blender. Lightwave doesn't handle dForce hair, but Blender does.
