The obvious cause of the error saying useNavigate may only be used in the context of a Router component is calling a router hook outside the provider, for example from a modal mounted through a separate React root.
The less obvious cause is two copies of react-router in the dependency tree. Context identity is per module instance, so the hook reads a different context object than the one the provider populated and finds nothing, even though a provider is directly above it in the tree. Check with npm ls react-router or the pnpm equivalent and look for a library pinning a different major.
Fix it by deduping rather than restructuring the tree: resolve.dedupe in Vite, an overrides or resolutions entry, or aligning the range. During a partial v7 migration, importing some symbols from react-router and others from react-router-dom is another way to end up with mismatched instances.
