Describe the bug

So, i have this issue in Neovim, whenever i try to save a file using :w, the syntax (indentation, line etc) becomes "broken", what i mean is that, let's say I'm write a C++ file, in a line that has:

void somefunction() {
    std::cout << "Hello, idk" << std::endl;
}

when i press :w, the part become little bit unreadable:

void somefunction() { std::cout << "Hello, idk" << std::endl; }

see, why?, can someone explain it to me? how do i fix it?

What is the severity of this bug?

minor (annoyance)

Steps To Reproduce

Expected Behavior

when pressing :w, the file should saved and the syntax remain untouch.

It looks like you have a LSP server configured for cpp, and that it is being used to format the file. If you don't want it to format the file, disable LSP formatting for cpp.
