My pip has corrupted after trying to install Apache Airflow. Every time I am trying to use it I am getting the following message
Traceback (most recent call last):

Based on this answer, I need to downgrade cryptography. However I cannot do it using pip since I am getting the same error. I tried to download to my Ubuntu the wheel file from here; specifically cryptography-38.0.4-pp39-pypy39_pp73-manylinux_2_28_x86_64.whl. However, when I extracted it, there was no setup.py file inside it. The only way I can imagine installing it without using pip is moving the extracted files to the place python libraries are stored. However I cannot find the place where the old cryptography library was installed.
How to install the specific version on my machine without using pip and considering there is no setup.py file?
I found out where old cryptography library was installed using:
python3 -c "import cryptography; print(cryptography.__file__)"
I deleted the folder and pasted the cryptography version 38.0.4 that I had downloaded from the link above.
