According to the compatibility list the only supported device is the FGRGBW-101, which I think might just be an older model of what you have, probably has same settings and whatnot. I loaded up the system driver on a virtual device, there are pretty much no settings on there. So I have no idea what it is doing under the hood.
Have you tried setting the level for each channel to 100 from the system driver? Did it just get dimmed down to 1% somehow?
I don't think my scanner tool or the ZEN31 driver could have even done anything that would have caused it to stop working.
If you want to dig into it more you could use the Basic Z-Wave tool to read all the parameter settings, and/or set them back to the defaults per the manual. Super basic Z-Wave parameter tool
Otherwise a reset and pairing it again should get you back to working as it was before. The Z-wave "replace" feature is not working right on 2.3.7 right now, if you would have used that, so you may need to pair it to a new node.
