Why do I keep getting an error saying "Private route is not a route"?

Question

I am trying to make a private route and I get the following error: caught Error: [PrivateRoute] is not a component. All component children of must be a or <React.Fragment>

The first two code blocks are two DIFFERENT attempts at trying to solve the problem with the PrivateRoute. None of which worked. I found some other solutions to the problem here on SO, but they are outdated. Any suggestions?

const PrivateRoute = ({ children, ...rest }) => {
  const { currentUser } = useContext(AuthContext);
  return currentUser ? children : <Navigate to="/login" />;
};

const PrivateRoute = ({ children, ...rest }) => {
  const { currentUser } = useContext(AuthContext);
  // return currentUser ? children : <Navigate to="/login" />;
  return (
    <Route
      {...rest}
      render={({ location }) =>
        currentUser ? (
          children
        ) : (
          <Navigate
            to={{
              pathname: "/login",
              state: { from: location },
            }}
          />
        )
      }
    />
  );
};

        <Routes>
          <PrivateRoute>
            <Route
              path="form"
              element={
                <Form
                  deletePdfFromPreview={deletePdfFromPreview}

                  createBookletDb={createBookletDb}
                />
              }
            />
            <Route index element={<Navigate to="booklets" replace />} />
            <Route
