Hi @deleted-user-s_pSF_cCqVzk ,
Is this in ArcGISMap or ArcGISPro?
you can disable the back-end process, below are some links to help you with the disabling process.
ArcGIS Help 10.1, ArcGIS Help 10.1 - Foreground and background processing
By default, tools are run “in the background” meaning that while a tool is running you can do other stuff with ArcMap. When a conflict arises, the part of the code that does this (the background server) throws an exception (the actual technical term is “throws a wobbly”). You can fix this by going to the Geoprocessing Menu and looking for “Geoprocessing Options”. In the window that pops up, untick the Enable Background Geoprocessing:
The downside of this is that you won’t be able to do other work until the tool has finished its work.

I hope that helps.
This "solution" did not solve my problem in arc dekstop. Is there another known fix for this issue?
THIS WORKS!
