It seems that Clang-Format extension is affecting the C/C++ extension. That is when VS Code sends a format document request, either the Clang-Format extension or C/C++ extension will handle the formatting.

The C/C++ extension ships with Clang-format capabilities. You can set the C/C++ extension to use a specific Clang-format executable by setting "C_Cpp.clang_format_path" in settings.json and disable the Clang-Format extension. Could you try this and see if it still affects the C/C++ extension?
