Faces with holes no longer work in OCCT 7.6.0

Topologic is software that uses OCCT. By using OCCT 7.5.0, we are able to model and display a face with one or more holes (see attached images). The algorithm worked fine using 7.5.0, but it fails to create the correct face in 7.6.0 and instead, I get only edges. Can someone please take a look at the method Face.ByExternalInternalBoundaries (found at https://github.com/wassimj/Topologic/blob/main/TopologicCore/src/Face.cpp) and let me know if something can be changed to make it work again? Many thanks.
