USACE is no longer developing HEC-GeoRAS for Pro. Instead, (built directly into HEC-RAS 5.0.7+) does 90% of what GeoRAS did.
Because the official USACE development of HEC-GeoRAS slowed down after the release of ArcGIS 10.x, there is released by the USACE. The last major official release was typically built for ArcGIS 10.5 or 10.6. hec georas for arcgis 108 upd

For optimal stability, especially when using other HEC tools like HEC-GeoHMS, it is recommended to uninstall previous versions first and install Arc Hydro (e.g., 10.8.0.34) followed by HEC-GeoRAS. Key Features for Hydraulic Modeling
