Hi,


Please do understanding that we need the project .qar files to duplicate the Internal Error. We are not able to help you work around this Internal Error without the project files. You may try to simplify the design by remove any confidential code and shares us the design, as long as the design is able to duplicate the IE in the first place.


Best Regards,
