I think Khaled Ayed is right. In this configuration, the host calls RouterModule.forRoot several times, which should not be the case. So, this needs to be changed in any case.

If this does not resolve the issue, there may be another problem as well.

Can you please open an issue here:

Please also link a simple GitHub project reproducing the problem.

Best wishes,
