To me, this looks like you probably got an error the first time you started the app while it was creating the geoprocessing cache. The causes for this are often that the Python environment you are using needs to be recloned or just switch back to the default environment and restart the application.
When the cache cannot be built, all of the tools that run in Desktop mode (on your local system) will not show up in the GP pane. Only the tools that run remotely in the cloud or in your connected portal will show up, evidenced by all those hammers with cloud icons in your search results.
