Short answer
I have found this work-around for the problem:
Install and configure pre-commit in your base conda environment instead of your project's conda environment.
Details
I just reproduced this error a year later, getting an identical error log.
This happened when I was trying to run git commit with a Conda environment activated on Windows. While in that conda environment I was able to install packages, the mechanism by which pre-commit installs its hooks ended up broken, with SSL unavailable and the same log shown in the question.
The fix for me was to deactivate my conda environment, install pre-commit in my base conda environment, and do one commit with base activated. For some reason I still don't understand, SSL is available and works fine when pre-commit installs its hooks from the base conda env, but not from an activated project-specific environment.
Once the pre-commit hooks are installed and configured, then I can activate my project's conda environment and do further commits from there, since pre-commit reuses its cached installation of the hooks.

Here's the error log on my machine, identical to what we can see on the screen shot in the question:

I totally agree that this solution has bad smells: it's a work-around not a real fix. I agree that one should not install stuff in the base environment, and that all the project dependencies, including dev ones, should live in the project's venv. But... on Windows, this bug has affected both OP and myself.
