Closes #8329

This PR

• Adds Test to prove broken functionality / regression
• Updates to fix regression

Original Issue

• Regression found where Union type properties were not denormalizing when the first type does not match.
• This was caused by a new Exception being thrown with a Type Guard.

Solution

• Update the Exception type to be one that is caught by the union type handler.

Considerations

• NotNormalizableValueException being thrown after a security check doesnt make the biggest sense to me. However, InvalidArgumentException also does not make 100 percent sense either so I think it is okay. Other wise, we would have to create a new Exception and catch it, similar to NotNormalizableValueException.
