   ```
   -QLAlchemy 1.2.19
   ```
   
   This is likely your problem. For some reason you have a bogus package imstalled which replaces your sqlachemy.
   
   I am not sure what the package is, but it could be that you are the victim of "typosquatting" attack (https://nakedsecurity.sophos.com/2017/09/19/pypi-python-repository-hit-by-typosquatting-sneak-attack/). Some time ago published packages in PIP which were different by only one letter (hoping that someone will install them when they made a typo)
   
   Some people also had this package installed, so the above is likely:

   I convert it into discussion as it is not Airflow issue most likely
