Thanks for your post @PauloSantosBIM
I tried to load the webscene and the BuildingScene layer that you shared back into Pro 3.3. Unfortunately, this didn't work out either. The sublayers present in the "full model" that should contain features (not being empty) are throwing errors in ArcGIS Pro as well and not being retrievable.
Would it be possible to share the data with us? A file geodatabase containing the building layer should be enough or a Pro project file would also work well.
Further, which version of ArcGIS Pro did you publish the Building Scene Layer?
Did you try to publish the layer using the "cache on desktop" option?
Thanks.
