We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

There is no prior report of this error in our call tracking system which goes back over 10 years.  It does seem to be a fundamental modal solver error.  To determine the node numbers associated with an internal constraint equation issue the command celist,,,,conv immediately after the solve command and then save the database.  celist,,,,conv converts the internal constraint equations into external constraint equations which can be listed with celist,,,,conv.  If you are able to create a service request for this that would be desirable.
