arXiv submission \mathbb problem with mtpro2

Question

Update: Thank you for comments and warnings! I contacted arXiv support to be sure, and you are not allowed to use mtpro2.

I am trying to make a submission to arXiv, and I am using mtpro2 for my symbols. I included all the files like .map .sty .tfm etc.

Processing succeeds, however, all of my \mathbb{} symbols are printed as regular letters. What could be the reason? I would really appreciate it if someone could help me to identify the issue. I do not know what I need to provide.

Below I attached an example that compiles well on my end, but fails on arXiv:

\documentclass[11pt]{article}
\usepackage[dvipsnames]{xcolor}

\usepackage[scaled=0.92]{helvet}    
\renewcommand{\rmdefault}{ptm}  

\usepackage{amsmath}

\usepackage[subscriptcorrection,mtphrd]{mtpro2}

\usepackage{hyperref}
\hypersetup{
    colorlinks=true,
    linkcolor=blue,   
    filecolor=magenta,
    urlcolor=red,    
    citecolor=blue
}

\def\dbR{\mathbb{R}}
\def\dbV{\mathbb{V}}

\begin{abstract}
  To show symbols:
  \begin{equation*}
    \label{setvalued}
    \dbV: [0, T]\times \dbR^d \to 2^{\dbR^m}.
  \end{equation*}
  That is, for each $(t,x)\in [0, T]\times \dbR^d$,
\end{abstract}
