Trying to install but running into an error when opening in browser

[ForgottenLogic]

Im attempting to download Stable Diffusion but running into an error whenever I follow the final step on the guide. I can really use some help, ive spent the last few hours trying to figure it out, but I cant find out why it wont work. I have a NVIDIA GeForce RTX 4050 Laptop GPU. Ill list the steps I took below:

• I installed Python 3.10.6 from https://www.python.org/downloads/release/python-3106/.
  • I clicked add to path for installation
• I installed Windows GIT from https://github.com/AUTOMATIC1111/stable-diffusion-webui.git
• I installed Windows GIT (64bit under standalone) from https://git-scm.com/install/windows
• I installed CUDA Drivers from https://developer.nvidia.com/cuda-downloads
  • selected Windows, 11 and local
• Made a folder in Windows C labeled SD, and ran command https://github.com/AUTOMATIC1111/stable-diffusion-webui.git
• Clicked on file webui-user listed as type windows batch file (instructions said webui-user.bat but it wasnt listed that way)
• I typed into my Microsoft Edge browser url http://127.0.0.1:7860
  • It tells Hmmm..... cant reach this page and that 127.0.0.1 refused to connect
• The guide wanted me to click extensions, available tab, load and then install sf-webui-controlnet and deforum on the site
  • I could not do this, as the prior step said it couldnt reach the page.

During the installation process for these, a lot of information flashed across the screen as it downloaded. I am unfamiliar with these advanced setting with computers. However, I am taking my first steps into my first digital novel, and want to use the AI Generation system to complete it. Any help would be greatly appreciated!!!

After uninstalling and reinstalling following a different guide, ive gotten to the same point again. Ive found that when i click on webui-user (windows batch file), itll tell me theirs an error in the code that pops up on screen. It says

venv "C:\AI\stable-diffusion-webui\venv\Scripts\Python.exe"

Cloning Stable Diffusion into C:\AI\stable-diffusion-webui\repositories\stable-diffusion-stability-ai...
Cloning into 'C:\AI\stable-diffusion-webui\repositories\stable-diffusion-stability-ai'...

then it automatically opens git credential manager and ask me to login. I click to login with browser, it opens microsoft edge and says it either cant connect or itll say authentication succeeded and to return to application. but the command prompts on the black screen now says

Press any key to continue . . .

And when i press a key it closes out. No progress. Hope this info helps out with any ideas as to what my problem is and how to resolve it.
