Model Builder Error 000271 - Cannot use existing layers

[Rick_O_Hara]

I have some simple point layers that I'm trying to incorporate into a model. Why would my layers suddenly not work? The layers are fine. It doesn't matter where they are; if I drag them over from the catalog pane, they won't work either. I'm always struggling to get any tool to work from day to day. 

Thanks.

Add and connect data and tools and modify elements—ArcGIS Pro | Documentation

add map layers from map contents pane

add featureclasses from catalog pane

And are the point layers featureclasses in a local file geodatabase or some other incarnation of a point layer or are they added to the map from some other location.source?

Thanks @DanPatterson.

They are in a file geodatabase.

I just shut it off and on and started a new model. It was just an esri thing.
