LLDB cannot find python311.dll

Apply this workaround only when the installed lldb.exe reports unable to find 'python311.dll'. It is specific to an LLDB build requiring Python 3.11; other builds may require a different runtime.

Provide Python 3.11 through uv and add its directory to the current PowerShell session's PATH:

uv python install 3.11
$lldbPythonDir = Split-Path (uv python find 3.11)
$env:PATH = "$lldbPythonDir;$env:PATH"

Then run an already-built test binary under LLDB. This example assumes the release output path; adjust it to the active build configuration and replace SuiteName with the suite to debug:

lldb --batch -o "run --gtest_filter=SuiteName.*" -o "bt" -- build\windows\x64\release\unit_tests.exe

Save debugger logs and crash artifacts under temp/.
