Unable to format the file before saving it to the disk and vscode provided an wrong error message

[jht3QAQ]

Type: Bug

1.Create a file by File -> New Text File 2.write code: int main(){return 0;} 3.VSCode recognizes that this is a CPP file 4.use ctrl+shift+f to format this file 5.vscode report "There is no formatter for 'cpp' files installed" 6.use ctrl+s to save it to disk 7.now ctrl+shift+f can format this cpp file

I think saving to the disk is not important for formatting files, so I think this is a bug

Confirm this with JS and TS files too. For not saved files formatter doesnt work, only after saving them it works
