Why Can't I Use Calculate Geometry

Question

I have made an intersect with a raster I converted to a polygon and a buffer I made from a line feature. I would like to calculate the area of this intersect but am unable to do so. Would anyone know why this is this the case and anyway to solve the issue?

You can't calculate geometry into a Shape_area field if that is what you are trying since shape_length and shape_area are controlled by the geodatabase.

If your data are in decimal degrees, add a new field (double type) and use

Calculate Geometry Attributes (Data Management)—ArcGIS Pro | Documentation

there, preferably specifying a useful projected coordinate system to get your areas in planar units
