No signing certificate "iOS Development" found

After an upgrade of some kind (Xcode, iOS, ??) my app no longer loads onto my iPhone 11. I generated a new development.cer and double-clicked it. What's the next step to get my app to run on iPhone? It has been working for years, but no more. It runs fine in the simulator. Thanks.
