Hi,

Difficult to tell why this error happens. Is there a pop-up window or is the error only displayed in the log file? Can you give more information on how you created all these tie points? and how you exported them? For the export I suppose you right-click on the “GCPs/MTPs” in the left sidebar, but to be sure. What would you like to do with the exported points? 

Please share the entire log file through a file sharing service (Google Drive, Dropbox,…), maybe I can find something else there. If possible, also share the quality report of the project.  

Lots of questions, but that should help to understand the case.
