Additional Information

LLDB is in the PATH which is reasonable to use in this situation:

% which lldb
/usr/bin/lldb

Start by reproducing the debugger discovery with the reported Xcode paths and /usr/bin/lldb, using the lldb -v and which lldb commands from the report. Trace where the C/C++ extension searches for GDB and LLDB, then verify the issue is resolved when LLDB is available through PATH and the documented Xcode location is absent.
