I don't repro the issue. Is your setting "C_Cpp.clang_format_style": "xxx/.clang-format", specified using the proper file syntax like `"C_Cpp.clang_format_style": "file:/Users/user/Documents/folder/.clang-format"? Does it work for a .cpp file?

I checked the issue again. .clang-format is proper. The issue happens every time I reconnected with the remote machine by VNC, no matter which version I'm using. It seems that I can only fix it by: uninstall it, restart the VSCode(must), install it.

@chuan02162 It sounds like the C/C++ extension is not installed on the remote machine or our extension is failing to initialize and register itself as a format provider. If you check the Helpful->Toggle Developer Tools->Console there might be some error logging.
