I'm compiling LaTeX with MiKTeX. I get an ambiguous warning which interrupts compilation.

LaTeX Warning: Command \' invalid in math mode on input line 209.

209 > \begin{equation} M = \left\{ m : {R_n} \left[ a \right] \right\} \end{equation}

The same line compiles very well on Overleaf.

You may wish to try replacing \{ and \} in this instance with \lbrace and \rbrace - this should compile properly. So your equation becomes

M = \left\lbrace m : {R_n} \left[ a \right] \right\rbrace
