From other sied, typesystem_core_common.xml has twice definition of QMessageLogContext with different Qt versions:
<object-type name="QMessageLogContext" since="5.14"/>
<object-type name="QMessageLogContext" since="5.9" until="5.13.2">
<modify-function signature="copy(const QMessageLogContext &)" remove="all"/>
</object-type>
Therefore, I think, that my qt version is not defined and I included QMessageLogContext twice
