Solution
I have solved it airflow 2.4.0 and 2.3.4 has this bug but they will resolve it at the 2.4.1 update. You can also install 2.3.3 that is totally fine now I am using that.
SOLUTION [official] i. don’t use latest ii. use 2.3.3 - https://airflow.apache.org/announcements/ 1) Sorry if not clear, but this already happened in 2.4.0, which I installed today (It was fine on 2.3.3 and before). Running on Python 3.10.5. - https://github.com/apache/airflow/issues/26492#issuecomment-1251078527 2) ACTUAL FIX - https://github.com/astronomer/airflow/commit/af01ddf5b1c528c3de2c959c499e7289decc7a26
