Bug Summary and Steps to Reproduce

Bug Summary:

cpp files no longer get found in compile_commands.json, regression to 1.19.9

Steps to reproduce:

Activate cpp file, expect intellisense to parse and find include files. Get this error, switching back to 1.19. 9 fixes the issue:

[5/8/2024, 8:05:56 AM] "XBYCSCreatePoolData.cpp" not found in "e:\ws\3dbyme/.vscode/compile_commands.json". 'includePath' from c_cpp_properties.json in folder '3DBYME' will be used for this file instead.

Expected behavior:

File to be found, and intellisense to work
