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? – David Carlisle Jan 14 '23 at 10:02

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}
