Math breaking pdflatex build.

[AakashGC]

The following math:

$$
\begin{aligned}
 [\Pi &+ \beta^{1/2} L^{-1} \Lambda (I - \beta^{1/2} L^{-1}
\Delta_h)^{-1} \Theta_h]^\prime [\Pi + \beta^{1/2} L
\Lambda (I - \beta^{1/2} L \Delta_h)^{-1} \Theta_h]\\
&= [\hat\Pi + \beta^{1/2} L^{-1} \hat\Lambda
(I - \beta^{1/2} L^{-1} \Delta_h)^{-1} \Theta_h]^\prime
[\hat\Pi + \beta^{1/2} L \hat\Lambda
(I - \beta^{1/2} L \Delta_h)^{-1} \Theta_h]\end{aligned}
$$

Is breaking pdf build with jupyterbook-latex with the following error:

! Argument of \\aligned@a has an extra }.
