Can you provide raster and GCP points to reproduce ?
I am having the same problem. Seems something in the decimal places. Rasters are always moved to pixel spatial reference instead of projected coordinates.

Unfortunately i cant. Client's private overhead imagery.
I had to reproject my original raster from EPSG:31983 (UTM proj.) to EPSG:4326, georreference it and converted back to UTM.
So the issue occurs if the crs of the origin is the same as the GCP and the destination?

Sure, its a 209MB file though, I am uploading it to Google Drive if thats ok? Will send you a link once done.
I do have same problem, it is getting displayed in different part of the world after geo-referencing..Any solution?

This happened to me recently, if everything was in the same PCS e.g. UTM it did not georeference correctly. Do not know if related to this issue itself but since you asked I can confirm it did happened to me. I can't provide the source data unfortunately.
I'm experiencing the same issue. Depending on the transformation type used, the output is variously complete, clipped, or blank and always misplaced to somewhere in South America or off its western coast, instead of New York State. Tested with version 3.28.2-Firenze running on Mac OS 13.1 and version 3.28.1-Firenze on Windows 11. Orthophoto and Points File.zip
Thanks @Lugal-PCZ. Issue confirmed on Windows using QGIS 3.28.2. The issue doesn't occur using QGIS 3.22.
Current workaround is:
What is the bug or the crash?
Georeferencing an already georeferenced image that is slightly misalinged places it in a completely different part of the world.
Steps to reproduce the issue
0- Open QGIS 3.28.1-Firenze 1- From the Layer Menu, Open Georeferencer 2- Load an already georeferenced raster. 3- Create some GCPs on the raster and select their final location from the Canvas. 4- Transformation Type: Thin Plate Spline, Resampling Method: Nearest Neighbor, Target SRS: EPSG:32636 (which is the same as the raster itself and the project). 5- Start the georeferencer.
The georeferencer completes its task but the image doesn't show on the map. When I select its layer and select Zoom to Layer, it shows up in the middle of the jungle in Congo.
Performing the same procedure in 3.24.3-Tisler places it in the right spot with no issues.
