[andrewcrook]

macOS 10.15.5 Anki Version 2.1.26 (70784154) Python 3.8.0 Qt 5.13.1 PyQt 5.14.1 MikTeX Console 2.9.7429

• on the add new card screen when I change the card type I get the following error
• It doesn’t matter if the cards field are blank or not
• I have disabled all other add-ons so that "⁨Show LaTeX and MathJax result in editorbrowser⁩" is the only one.
• When I disable ⁨"Show LaTeX and MathJax result in editorbrowser⁩" Ankis internal LaTex support works.
