Hello. I have a similar problem that seems linked to the use of \nonumber in a math expression in a .md file.

Here after some details to reproduce :

• From an empty .md file, open preview to the side.
• Add in a ````math ` section

$$\begin{align} \nonumber A = B + C \end{align}$$

The rendering is OK

• Save the file.
• Close VSCode
• Open VSCode, open the .md file.
• open preview to the side. I have the error message.

Hi there. Are you using KaTeX or MathJax for rendering the math?

[Kariiboo]

Hi !
I use KaTex.

When I switch for MathJax, the rendering is OK.

Thanks for the details. I will look into the katex issue.
