Tensorboard not working with after upgrading tensorflow from 2.1.2 to 2.3.0

I was using TensorFlow 2.1.2 and TensorBoard 2.4.1,

import os, shutil
import tensorflow as tf
print(tf.__version__)

SUMMARY_DIR = 'summary/testing_this'
if 1:
    # SUMMARY_DIR is the path of the directory where the tensorboard SummaryWriter files are written
    # the directory is removed, if it already exists
    if os.path.exists(SUMMARY_DIR):
        shutil.rmtree(SUMMARY_DIR)

    train_summary_writer = tf.summary.create_file_writer(os.path.join(SUMMARY_DIR, 'train'))
    test_summary_writer  = tf.summary.create_file_writer(os.path.join(SUMMARY_DIR, 'test'))
    train_summary_counter = 0

for i in range(100):
    with train_summary_writer.as_default():
        tf.summary.scalar('train/sampled-softmax loss', i+5, step=train_summary_counter)                
        train_summary_counter += 1

The code written above worked perfectly fine. But as I upgraded to TensorFlow 2.3.0, the following error was thrown-
