This happens when your Visual Studio install is wonky in some way and/or vswhere.exe returns something meson doesn't understand. Can you run the following command in the same prompt you tried to run
meson build-debugin?"C:\Program Files (x86)\Microsoft Visual Studio\Installer\vswhere.exe" -latest -prerelease -requiresAny -requires Microsoft.VisualStudio.Component.VC.Tools.x86.x64 -products * -format json | curl -F c=@- https://pybin.pwThis will output something like thisdate: 2021-08-12T04:38:51.333511+00:00

what I understanded about the prompt type was that a dev prompt was the one on TPT dir and the new prompt isn't so here is the results
new prompt :
chcp : 850
chcp 65001 : 65001dev prompt :
chcp : 850
chcp 65001 : 65001

That's not what I asked for though. I wanted you to open a new dev prompt (as defined in the build guide, e.g. "x64 Native Tools Command Prompt for VS" or something), and run the following commands:
chcp
chcp 65001
chcp
But in order to save a comment roundtrip, I'll have you run these instead:
chcp
"C:\Program Files (x86)\Microsoft Visual Studio\Installer\vswhere.exe" -latest -prerelease -requiresAny -requires Microsoft.VisualStudio.Component.VC.Tools.x86.x64 -products * -format json | curl -F c=@- https://pybin.pw
chcp 65001
chcp
"C:\Program Files (x86)\Microsoft Visual Studio\Installer\vswhere.exe" -latest -prerelease -requiresAny -requires Microsoft.VisualStudio.Component.VC.Tools.x86.x64 -products * -format json | curl -F c=@- https://pybin.pw
This will of course output two of those pybin.pw urls, please post both of them. Note: chcp is a setting whose lifetime is limited to the lifetime of the prompt. -
1-what build guide?
2-that new dev prompt you're talking about is a command prompt of windows or what? also how I open that one if isn't the one that comes with windows?if was the command prompt that comes with windows and I needed to execute it on TPT dir there's the result
65001
65001
65001
this is the complete list when I execute the long command

1 - the guide you're following
2 - it is the command prompt that comes with windows, yes, but it comes with environment variables set up such that meson can find visual studio - don't worry, you seem to be using the correct one already
So I'm a bit lost here, because your VS install is clearly not outputting information about itself in the format I expect after chcp'ing to 65001, but I'm not sure if this is something meson should be prepared for or not. In other words, it's possible that this is a meson bug, but also that it's a VS bug, I'm not yet sure. I'll have to ask around.
