Solved. Cura can't seem to use support blocker if you are printing from nozzle #2.

Check the "Support horizontal expansion" setting for your second nozzle. Set it to 0.

Sorry, I went and got a different print running. I'm not sure I see that setting you are referring to.
Both nozzles seem to have the same settings

Update though, if I have both nozzles enabled it will generate correctly. If just nozzle 1 is enabled, it also works. But if I only have nozzle 2 enabled is when the error shows up.

@Annoyed123x support blocker is also assignable per extruder and by default it is assigned to extruder 1 when you add a support blocker, so if you're printing with only the second extruder, you need to select the support blocker and assign it to the second extruder as well.
That should resolve the issue.
just click on the support blocker and then assign it to extruder 2:

That's the one. Didn't realize I needed to reassign the blocker also.
