State in redux form doesn't change - reactjs

Question

The state doesn't change in my react form. console.log(renderselect) doesn't have a value - it shows undefined.
I tried everything but there are no changes.
import React from "react";
import {Field, reduxForm} from "redux-form";
import {connect} from 'react-redux';
import {renderTextField, renderField, validate, warn, renderselect} from "../../../Components/Forms/renders"
class SyncValidationForm extends React.Component {
constructor(props) {
super(props);
this.state = {
errors: {},
opencheck: "hallo"
}
this.handleSelect = this.handleSelect.bind(this);
}
handleSelect = (value) => {
this.setState({"opencheck": value.target.value});
};
render() {
const {handleSubmit, pristine, reset, submitting, opencheck} = this.props;
console.log(opencheck);
return (<form onSubmit={handleSubmit}>
<div className="box-body">
<div className="row">
<div className="col-lg-3">
<Field className="form" name="favoriteColor" label="Maak eerste een keuze" component={renderselect} options={{
"Geen informatie" : 'Geen informatie',
'Altijd open' : 'Altijd open'
}}
onChange={this.handleSelect}/>
</div>
</div>
</div>
</form>);
}
};
SyncValidationForm = reduxForm({
form: 'insertstart', enableReinitialize: true,
warn
})(SyncValidationForm);
const mapStateToProps = state => {
state => ({
initialValues: { favoriteColor: 'Geen informatie' }
})
}
export default connect(mapStateToProps)(SyncValidationForm)
The selected box must change the state, but there are no changes. Also, in the first render, the opencheck in console log has no value.

You are conflating Redux state (which is mapped to your React component's props in mapStateToProps) with the built-in React component state which has nothing to do with Redux. Before continuing you may wish to read these links to fully understand the difference:
Redux: Organizing State
React: State and Lifecycle
It's often confusing and frustrating that both of these commonly-integrated libraries both call their data source "state", but it will be important for your to understand the difference and identify which one you are using.
If you want to use Redux to store the selected state, your handleSelect function needs to dispatch the new value to the Redux store, typically by using mapDispatchToProps to dispatch an action, not by calling this.setState
If you want to use React component state, then you need to refer to this.state.opencheck in your render() function, not this.props. opencheck.
