3You don't need to post the whole code, we need a MWE that we can help you. Otherwise we have no idea which packages you're using, where this character occurs and so on. – Steradiant Jun 11 '20 at 09:49

Did you copy-and-paste text from some other document into your LaTeX document? – Mico Jun 11 '20 at 09:50

One of your expressions uses (U+1D434), the Unicode mathematical alphanumeric symbol italic A, instead of A. This is probably because you copied from a PDF made with unicode-math or mmap or a webpage that uses MathML and pasted into your source file.
The simplest answer is to compile with LuaLaTeX or XeLaTeX and load \usepackage{unicode-math}.
Otherwise, you can try to load newunicodechar and add the rule
\newunicodechar{}{\mathnormal{A}}
This might or might not work in all engines, due to being outside Unicode’s Basic Multilingual Plane. (Thanks to David Carlisle for a good suggestion.)
Finally, you can search-and-replace every instance of in your document with A.
