I am facing the same problem but with a different module on this communication toolbox.

While I can run the QPSKModulator without any problem, I obtain that same error when trying to run the demodulator.

So, this works:

qpskMod = comm.QPSKModulator;

But this line complains that the mcompskdemod.mexw64 file cannot be found:

qpskDemod = comm.QPSKDemodulator;

I will answer myself in case it is useful for someone else:

It looks like the antivirus is blocking some of these files, that is why Matlab cannot access them.

Cheers,
