Do you disagree that where a solvent causes an amorphous polymer to
craze, this is because the polymer is principally soluble in it?

This is environmental stress cracking. It's not the polymer being
soluble in the solvent. If anything, it could be regarded as the solvent
going into solid solution in the polymer, changing its fracture behaviour.
