Given that you have no closing } after the \thesubsection but right at the end you are attempting to redefine
the macro \thesubsection{\thesection.\Alph{subsection}}.

It doesn't exist so LaTeX throws an error (it's not a warning but an  error; see exact message in the .log file).

Even if the macro had existed you would have ignited another error. \renewcommand expects a second argument.

You gave the correct syntax for your case at the end of your post.
