Start by comparing the valid and invalid path screenshots with the launch log, especially the sourceFileMap, cwd, program, and GDB connection settings. Reproduce the intermittent failure on Windows 10 with the listed VS Code C/C++ extension and Cygwin GDB versions. Done means identifying why the path becomes invalid and restoring reliable ICE debugging.
