@All, we created a community post where we will post the latest updates about [Desktop] [Pix4Dmapper 4.3.27] Project shift when reopening a project .
@Vallez, if the shift after introducing the GCPs is very big, it can happen that the view needs to be recentered again. Could you check if you can see the project when selecting one object in the Layer section and use the hotkey F? More information in the An object is located far from the model article.
