Unfortunately your example is far away from being minimal! – user1146332 Apr 02 '20 at 20:41 — user1146332, Apr 02 '20 at 20:41

Add the relevant part of fontmath.ltx to your document preamble, with some changes.

\documentclass{article}

\DeclareSymbolFont{sansletters}{\encodingdefault}{\sfdefault}{m}{n}
\SetSymbolFont{sansletters}{bold}{\encodingdefault}{\sfdefault}{bx}{n}

Uppercase letters are declared as belonging to the sansletters math symbol font. You can still override the typesetting in particular cases with \mathrm or similar.

If you need boldface sans serif letters, you can't use \mathbf. Instead, load the bm package (after amsmath) and use \bm{A} for a boldface sans serif A.
