I have the simplest Flask application, I found a behavior that is incomprehensible to me, I'm curious what this is connected with, I hope that someone will clarify. The bottom line is this: when adding a test (test = SelectField(u'Test', choices=[('0', '0'), ('1', '1')]))), even an unused SelectField field to an object, the application stops responding properly to pressing the submit button, just refreshes the page, does not write anything either to the console or to the web.
run.py

from flask import Flask, render_template, flash
from flask_wtf import FlaskForm
from flask_wtf.csrf import CSRFProtect
from wtforms import SelectField, SubmitField


app = Flask(__name__)
csrf = CSRFProtect(app)

class Config(object):
    SECRET_KEY ='123123123qweasdzxc'

app.config.from_object(Config)

class Exploits(FlaskForm):
    test = SelectField(u'Test', choices=[('0', '0'), ('1', '1')])
    language = SelectField(u'Programming Language', choices=[('cpp', 'C++'), ('py', 'Python'), ('text', 'Plain Text')])
    use = SubmitField('Выбрать')


@app.route("/", methods=['GET', 'POST'])
def home():
    form = Exploits()
    if form.validate_on_submit():
        print('SUBMIT!!!')
        flash('Botton is submited {}'.format(form.language.data))
    return render_template('index.html', form=form)



if __name__ == "__main__":
    app.run(debug=True)

index.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
{% with messages = get_flashed_messages() %}
{% if messages %}
<ul>
    {% for message in messages %}
    <li>{{ message }}</li>
    {% endfor %}
</ul>
{% endif %}
{% endwith %}
<form action="" method="post" novalidate>
    {{ form.csrf_token }}
    {{ form.language }}
    {{ form.use }}
</form>
</body>
</html>

In my opinion it should be like this.
Instead ofif form.validate_on_submit():
And call request
from flask import request
