Hi @BigBigOranges,

Please first ensure that the output shapefile of Geo-SAM is correct. It is recommended to directly click on ... after Output Layer or File option to select a path and create a new one. If the issue persists, please download the main library code and replace the original code to test it.

Replacing the main program code has solved the problem. Thank you for your answer.
