I'm playing on 1.19.3. When pressing K to open he GUI, the game instantly crashes. All other features works as expected and auto-reeling fuctions normally. Further experimentation shows that the problem isn't because of other mods.

Fixed with v5.0.3. Should be available on CurseForge soon.

Glad it's not just me.
For now just unbind the key to avoid accidentally causing a crash whilst playing. (Use ESC to clear the key during the binding process.)

I have the same problem.
Fortunately it still maintains basic jobs.
