Error on startup after install

[greggdonovan]

I got this error on Anki startup on MacOS after installing. The issue goes away after disabling the plugin. Any ideas? Thanks!

Error
An error occurred. Please start Anki while holding down the shift key, which will temporarily disable the add-ons you have installed.
If the issue only occurs when add-ons are enabled, please use the Tools > Add-ons menu item to disable some add-ons and restart Anki, repeating until you discover the add-on that is causing the problem.
When you've discovered the add-on that is causing the problem, please report the issue to the add-on author.

Thank you for reporting this.

Could you share with me your Anki collection, so that I can check myself what's going on with that notetype? I think just receiving the card templates should be enough to figure it out.

anki.errors.CardTypeError: Card template ⁨1⁩ in notetype '⁨2. Mnemonics⁩' has a problem.
See the preview for more information.

This error message is ambiguous, but the code message tells me it's probably that this plugin's modification mangles the template (source).

Notes to self:

• [ ] Design proper error handling for template modification.
• [x] Notify upstream that the error message itself could use an improvement (DONE).

Thanks for the reply, @gregorias! It turns out I had a broken note type locally - it was a note type that used LaTeX, but I had no LaTeX installed (new laptop). Once I fixed that the problem went away... And thanks for the plugin, it's great!
