I was joining a huge table to a layer, the join was fine and i tried exporting the layer as a new feature class, everytime i tried running it, it was stuck at 6% initializing. I have also tried using other geoprocessing tool such as spatial join, and it wouldnt work as well
Where are you saving the output to if the join worked? Is it to a local folder or geodatabase location?
What are your machine specs? are they just good? or do they exceed the recommendations
