Profession and trades crashing the game.

I made this villager profession in the 2023.2 update. I also added some trades to it. My game simply would not load a world. I did some testing, and I discovered that the trades, when given to existing villager professions, are perfectly fine. My custom profession is also perfectly fine by itself. Combining the two, however, is a recipe for disaster. If anyone knows why this is happening or a possible fix, please let me know!

Thanks!
