The ArcGIS Pro Add Spatial Join tool fails on subsequent runs when attempted on the same target layer with a period key (.) as the special characters.

Workaround

1. Expand the Folders > Project folder > scratch.gdb in the Catalog pane.
2. Users can see the "abc_AddSpatialJoin".
3. Right-click and delete it.
4. Run the Add Spatial Join tool again with the same parameters.
5. The tool runs successfully for the subsequent time.
