I just upgraded from 2.7 to 2.9 and now every time I run a geoprocessing tool in jupyter notebook (I have python 3.7.11), I get ERROR 000464. I have no instances of pro open and I have restarted over and over. Here is what I am running when it goes wrong and I get the error. It worked fin until the update, so I'm not sure if I am needing to change something or if it is a bug.
Thank you
