Ideally, you should rescan the whole object using a better approach. The input data is critical for a successful project. We have resources on how to take the photos. If you need so many control points, the input data is not good. When images are taken properly, there is no need for control points.
I really can’t tell from the screenshot, but I suspect you took photos like you would for a panorama. That is not correct, you need parallax. Each photo needs to be taken from a different position. Use a drone or a long pole to scan the facade
The large errors for point 18 indicate that you either misplaced the control point or that there are significant misalignments. I would delete it and start placing it from scratch.
