This is a strange error. It was trying to save a session with a dicom and lots of gltf models open and it says that a gltfmodel subnode pointed back to its parent gltf model creating a cycle that is not allowed in sessions. Saving gltf in sessions used to work so I suspect there is something special about your gltf. You could try just loading the gltf models and saving a session (.cxs) file, no vr. If that fails then try cloaing half the models and see if that will save. It could be just one model causes the issue.

It was trying to save a session to send to another meeting participant.

Fixed.

Session saving with a GLTF model open always failed with this error. It surprises me that this was never reported before. This was a bug in the session saving code for Generic3DModel which was a base class for the GLTF model. I changed it so the GLTF model uses Surface as a base class instead. I also changed OBJ models to use Surface as a base class all though OBJ saved in sessions even with the old code because OBJ does not support model hierarchy which was needed to see this bug.
