No platform feature enabled. Please enable one of the follow

Error message

No platform feature enabled. Please enable one of the following features: liveview, desktop, mobile, web, tui, fullstack to use the launch API.

What it means

The launch API was called but no renderer feature (web, desktop, mobile, liveview, tui, fullstack, native) is enabled on the dioxus crate, so there is no backend to launch. The builder's platform detection fell through every cfg! check.
