Try downloading the "Windows embeddable package (ARM64)" from https://www.python.org/downloads/release/python-3111/ and extracting it into the LLVM bin directory.
The official release doesn't include a matching Python environment. IIRC similar confusion had come up more than a few times in the past.
thank you
Note that this happens also for the more popular x64
version of LLVM installer. It's not just an arm64
oversight.
It makes lldb.exe
on Windows unusable (if you don't have the python version used to build lldb installed)
https://github.com/llvm/llvm-project/issues/59524 would be the corresponding x64
bug report.
A different way to fix the issue would be to ask the package manager to overcome this issue. winget
is one such package manager for Windows. I've opened up a ticket for not picking the arm64 packager for LLVM here.
Note that lldb does not use only the "binary compatible" portions of the Python C API's. There was an experiment a while back to try to do all that we need to do with that restricted set of the API but it didn't get very far. My experience on other platforms is that if you have even fairly small version skew between the Python lldb was built against and the one that it loads causes weird behaviors and often crashes. We've even seen this happen where the Python versions were the same but the two pythons were built differently. So long as that it true, I don't think we want to encourage people to use a Python that isn't the version we built against.

Qt Creator needs for its binary CDB dlls to ship Python3.1x.dll
and a Python3.1x.zip
file with precompiled standard library.
https://github.com/qt-creator/qt-creator/blob/master/cmake/CreatePythonXY.cmake is the CMake code that creates the Python3.1x.zip
file.
It would be awesome if lldb.exe would get the same treatment, install the Python dll used for compilation and precompile the Python standard library and make the zip file.

I installed LLVM-15.0.6-woa64.exe on the surface pro-x machine and ran lldb. An error occurs as shown below.
