Hi @AakashGfude and @mmcky, the 3rd issue is that in lecture wald_friedman
- there are extra $>$ symbols in a math expression.

Please see their rst and myst files respectively (left: rst, right: myst):

It seems that the >symbols are added during translation, which might be read mistakenly by latex.
