Create virtualenv failed when build with automate-git.py

[yuki]

Hello everyone,

I've been working on compiling CEF using the `automate-git.py` script and encountered an issue related to the creation of the virtual environment that I'm unable to resolve. Despite upgrading Python to the latest version, the problem persists.

Here's the specific error message I encounter:

```

```

Interestingly, I don't have the `C:\Users\[username]\AppData\Local\Temp\vpython_bootstrap733727795\packages\virtualenv-15.1.0\virtualenv.py` file or even the path on my computer.

To give you an idea of my setup and the command I'm using to compile, here they are:

```
set GN_DEFINES=is_official_build=true proprietary_codecs=true ffmpeg_branding=Chrome
set GYP_MSVS_VERSION=2022
set CEF_ARCHIVE_FORMAT=tar.bz2
python3 automate\automate-git.py --download-dir=F:\code\chromium_git --branch=4389 --minimal-distrib --client-distrib --force-clean --x64-build
```

I've tried upgrading Python to address this issue but to no avail. It seems like the problem is not directly related to the Python version.

Has anyone encountered a similar issue or have any suggestions on how to resolve this? Any help or insight would be greatly appreciated.

Thank you in advance!

It may depend on the OS but as far as I'm aware (and no I'm not a mastah) you may need to roll back the Python version to like 3.10.x because there is some change to API somewhere,, see if that helps anyway
