Pre-commit install-hooks does not work (SSLError)

I use conda Python environments. Whenever I try to run pre-commit install-hooks, I get the error

 Could not fetch URL https://pypi.org/simple/ruamel-yaml/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded w
ith url: /simple/ruamel-yaml/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) - skipping

...

WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

However, pip works just fine when I use it.

I already tried pre-commit clean, uninstalling pre-commit and reinstalling it (either with conda or pip), updating pip, switching off the VPN, and also any other solution I could find on Google. Nothing seems to work. Could you please help me?

The .pre-commit-config.yaml looks like this:
