Hi, I’m sorry you’re getting a crash of the addon. Can you write to me via email or on Telegram, so I can support you and fix the issue?
**Update: in the addon you can find only UNICODE approved emojis https://unicode.org/emoji/charts/full-emoji-list.html, so your linked emoji is not part of those standard and I cannot add it, I'm so sorry
