Quartus Prime Pro 19.2 quits unexpected with following error report. Does anybody know, what's the problem in this case?

Problem Details Error: Internal Error: Sub-system: CDB_SGATE, File: /quartus/db/cdb_sgate/cdb_sgate_component.cpp, Line: 926 Port direction does not agree. Stack Trace: 0x5f4ac: CDB_SGATE_COM...

Cleaning the project didn't help.

As I want to evaluate the update from Cyclone V to Cyclone 10 GX it is a project generated with Quartus Prime 18.0, which I tried to migrate to Quartus Prime Pro 19.2.

IP Generation -> O.K.

Analysis & Synthesis runs fine until "Creating instance-specific data models and dissolving soft partitions" where it crashes.

It must be design-related because trying to compile a Cyclone 10GX example design worked without any problem.

I can provide you with the archived project, but not in the community.
