Katex-Rendering broken in my hugo version (v136.4)

I found some other entries where this issue is explored.
I know for sure that it worked previously on an older version (but dont know the version)
So it happens that parts like

\[A \lor B = Q\] 

or

["latex","../images/electronic_basics/ohms_law.svg" ,imgfmt="svg"]
\large \[ R [\Omega] = \frac{U [V]}{I [A]}\]

become not rendered in the output html, normally they should end up in an image.
Please let me know what I am doing wrong here…

Who implemented the math support? You or the author of the theme you are using?

This approach works great with v0.122.0 and later:

This markdown:

\[A \lor B = Q\]

Is rendered to:

image


Also, as you and I have discussed in the past, when posting in this forum please wrap code, data, and configurations within triple backticks, or use the </> button in the menu. I have fixed your posting.
