I am having trouble installing Stable Diffusion web ui.

[Ki-git43340]

This is my first time to ask a question.
Thank you in advance for your help.

What I would like to solve.

An error occurred during the installation of Stable Diffusion.
The cmd opens and closes momentarily and I run it as administrator and see the following error code.

Problem/error occurring.

C:\Users\(Username)\AppData\Local\Programs\Python310\python.exe: can't open file 'C:\\c': [Errno 2] No such file or directory
Creating venv in directory C:\SD\stable-diffusion-webui\venv using python
Unable to create venv in directory "C:\SD\stable-diffusion-webui\venv"

exit code: 9009

Cause.

The initial installation and running went well, but I deleted the Python path in the Path in my windows environment variable.
At that time, Stable Diffusion could not start, so I uninstalled Python, deleted the Stable Diffusion folder, and reinstalled it, and now it is as follows.

Environment

Windows 11 Pro
64-bit operating system

What I tried by myself

1. Open webui-user.bat in Notepad, write the full path of Python and run it.
   set PYTHON=C:\Users(Username)\AppData\Local\Programs\Python\Python310\python.exe

2. Reinstall python(3.10.6), git and storable diffusion

3. When installing python, check the box for "□Create a path" and install using the recommended settings.

4. Stable diffusion is checked alternately with the latest version and version 1.5.

Thank you in advance.
