ArcGIS Pro- Legend for Layer Corrupts- Has anyone experienced this?

[Amanda__Huber]

Hello, 

We recently ran into an issue where a layer in our map displays in the map but will not show up in the legend. We opened an Esri support case and they were just as baffled after 2 hours of troubleshooting. 

Has anyone ever experienced this behavior? We're using ArcGIS Pro 3.2.2 and we've tested creating a new legend, copying the layer and trying to get it to show up in the legend, and so much more.

Below is a screenshot of the issue. All the icons show up in the map with no problems (black square icons), but both legends (new and old) are completely broken and refuse to display the layer. 

Thanks to anyone who can provide any sort of info. 

Best, 

Amanda Huber
