I am creating a python code testing (pytest) website using django and deploy on azure and I just test a code and try to delete files in the root directory of my project using shutil.rmtree() but It returns code like this

and it didn't delete a file. Also, I interpreted os.chdir("..") and then tried to delete files this time code even don't run and give a server-side error. This error didn't solve by refreshing the page instead I had to restart azure server.
How Azure or any other web hosting platform protects files from getting deleted and if any file delete then which files may get deleted?
