When I search certain enchants in the trading post my game crashes. (See crash log)

I typed "luck" and it showed three results then crashed immediately. I have found no correlation between what I type and crashes yet. I can just type "unbreak" sometimes and it will crash.

Which enchants exactly, I mean what exactly did you type that made the game crash?

Looked into it, that's a bug with the Blue Skies mod.
I created an issue on their bug tracker, let's hope they'll fix it soon: https://gitlab.com/modding-legacy/blue-skies/-/issues/84
