@ThomasT this crash is happening within a macOS API, so is outside of Alfred's control.

 

Have you installed any custom dictionaries on your Mac, or made any customisations to the dictionary?

[ThomasT]

@Andrew Indeed I had additional dictionaries installed. It seems the update to Monterey broke something in DictionaryServices. After removing these dictionaries the crash is gone. Thanks for putting me on the right track.
