I am attempting to convert some labels on a map to annotations in ArcGIS Pro 2.0 using the new Convert Labels to Annotation tool, and the system is hanging for 10+ minutes every open that tool or attempt to change the tool settings ("Input Map", "Output Geodatabase", etc.). This is a fairly big project, but the map I have open is simple- only 10 layers, 4 of which contain labels. We're talking ~18 labels total.
I tried starting a brand new project just to test the tool, and everything ran very quickly, so what is causing the tool to hang on my project? I suppose a better question is: what is the Convert Labels to Annotation tool attempting to access when it opens? Every map within a project (open or closed)? Every GDB associated with a project?
