Looks like you are end up in https://github.com/dealii/dealii/blob/dfff93f072b477d83183acbb4c0958b37930e157/include/deal.II/distributed/tria.h#L1071-L1076 which is a branch used when deal.II was configured without p4est. https://github.com/dealii/dealii/blob/dfff93f072b477d83183acbb4c0958b37930e157/examples/step-55/CMakeLists.txt#L40-L57 should have prevented you from configuring step-55. Can you confirm that your deal.II configurations indeed satisfy the requirements for step-55?
