Hello everyone I'm a newbie trying to use Stable Diffusion :'( I tried to launch it for the first time but it got stuck each time to this error, I honestly don't really know what i'm supposed to do right now.

Seems you have to reinstall httpcore in version 0.15
pip install --force-reinstall httpcore==0.15
works as a temporary workaround until some other fix is found. That or just append it to your requirement.txt This comes from a recent update in httpcore and nothing related to this repository.
Source:
I solved this issue by adding the below line in pipfile
httpcore = "<=0.15"
that is the solution for who using pipenv
Don't feel bad, for me it starts right up in windows. But I've tried several distros and installations since Aug and it has never run once.
update:I kept banging away at it, and it finally worked! I just made this I ran it with "python launch.py" and every time an error popped up I searched for it and applied the recommended fix...good luck!
