total guess but I wonder if your initial commit message might have a hidden space character in it. Can you try to modify the message and make sure it has no extra spaces?
(also usually a simple ‘git log’ is all you need to see your prior commits)
Are there any other failing tests?
You can also click on the OUTPUT tab (two tabs left of the terminal tab) and see if there are any error messages logged there.
Edit: also as I noticed you are not using an english language vs code, please switch to an english language keyboard and redo the commit message in case one of the letters you typed in is not an exact match to the english language keyboard value of the same letter.
