I am trying to type an uppercase theta symbol with the mtpro2lite package, but it doesn't appear properly, in its place is a black box. I moved the times package after and it appeared, but the numbers are all in the Computer Modern family. Is there any way that I can solve this problem?

Here is the MWE:

\documentclass[fleqn]{book} % It's just the environment I'm working with, it shouldn't matter.
\usepackage{bbding}
\usepackage{times}
%\pdfmapfile{=mtpro2.map}
\usepackage[lite,subscriptcorrection,slantedGreek,nofontinfo]{mtpro2}
\usepackage{hyperref}
\usepackage{amsmath}
\usepackage{titling}
\usepackage[dvipsnames]{xcolor}
\usepackage{makeidx}
\usepackage{tabularray}
\usepackage{emptypage}
\usepackage{graphicx}
\usepackage{algorithm}
\usepackage[noend]{algcompatible}
\usepackage{hvlogos}
\usepackage{csquotes}
\usepackage{caption}
\usepackage{mdframed}
\usepackage{breqn}

\begin{document}
Theta: $\Theta$.
\end{document}

    it would be a lot easier to help if you showed an example, a complete document with \begin{document} theta $\Theta$\end{document} and whatever preamble is required to show the issue and without all the unrelated packages. latex will not drop characters with no warning, what does the log show?

This is not really related to mtpro and not related at all to most of the packages shown. times is an obsolete package dating from the 1980s, use newtxtext for a more complete times clone.

enter image description here

\documentclass[fleqn]{book} % It's just the environment I'm working with, it shouldn't matter.
\usepackage{bbding}
\usepackage{newtxtext}
%\pdfmapfile{=mtpro2.map}
\usepackage[lite,subscriptcorrection,slantedGreek,nofontinfo]{mtpro2}
\usepackage{hyperref}
\usepackage{amsmath}
\usepackage{titling}
\usepackage[dvipsnames]{xcolor}
\usepackage{makeidx}
\usepackage{tabularray}
\usepackage{emptypage}
\usepackage{graphicx}
\usepackage{algorithm}
\usepackage[noend]{algcompatible}
\usepackage{hvlogos}
\usepackage{csquotes}
\usepackage{caption}
\usepackage{mdframed}
\usepackage{breqn}

\showoutput
\begin{document}
Theta 123: $\Theta 123$.
\end{document}
