Config window error on Anki 2.1.29beta1

[amazeum]

It appears there was a change in how some windows are rendered in Anki 2.1.29beta1. This is the error message from trying to pull up Special Fields on Anki 2.1.29beta1 on macOS 15.15.6:

Error An error occurred. Please start Anki while holding down the shift key, which will temporarily disable the add-ons you have installed.

@johnpincock It seems to be working great on 2.1.29 stable. Thank you for the quick turnaround! 🥇
