We've ruled out some variables that may be causing the failure. We're assuming the issue has to do with probing/reading xyz coordinates.
The program does work without applying a probing/rotation cycle.

If you see and potential issues in the code, if you could please point it out.

The error 304 is happening on this line:
N235 G18 G2 X-3.7632 Z-0.0197 I0.05 K0.

Probing looks just fine. Probably coordinate rotation is causing the problem. As the machine performs OK without probing/rotation, apply just G68 command for small arbitrary angle (.2 deg for example) and run the arc command. This way you will isolate the rotation impact from probing impact.

Thanks PROBE!
We tried just running the G68 command, less than 0.5 degrees, but have the same error.
I believe it has to do with rotating the ZX radius plane
 
You may be right, in the post I set the radius to use R instead of IJK, which worked.
However this isn't a permanent solution.
Is there a way to get around this limitation on a Haas?

Instead of rotating the coordinates, I would try helical interpolation. Not enough information (X starting point of the arc)is given. Nevertheless, once you calculated the angle, calculate the difference between Y at X starting point of arc and Y at X end point of the arc. Store as #104. Then perform:
G18 G2 X-3.7632 Z-0.0197 Y#104 I0.05 K0.
