Additional Information
The COM-based object system used by ArcGIS for many of its types is incompatible with the Python faulthandler module. To use Python Developer mode, explicitly disable faulthandler by adding faulthandler.disable() at the top of the code, or include the same in a PYTHONSTARTUP script.Workaround
Complete the workflow outside of Developer mode.
