Matlab uses comma not ; Parameter names are without spaces. And you have an extra ) that doesn’t have a ( to match it.

qamMapper = comm.RectangularQAMModulator('Modulator0rder', 2^bitsPerSubCarrier, 'bitinput', true, 'NormalizationMethod', 'Average Power');
and if you want to split it over several lines,
qamMapper = comm.RectangularQAMModulator('Modulator0rder', 2^bitsPerSubCarrier, ...
'bitinput', true, ...
'NormalizationMethod', 'Average Power');
Note that comm.RectangularQAMModulator is going away, and it is recommended that you convert to qammod(). See https://www.mathworks.com/help/comm/ref/comm.rectangularqammodulator-system-object.html#mw_7ac8462e-0cd3-43aa-a9ff-2033c3c46d37
