Um, I created a new world (still using forge) with the same mods as last time but have added make bubbles pop, sinytra connector, forgified fabric api, better end (fabric), and wakes (fabric) and after exploring for 10 seconds my game has crashed with the same error. I assume it is because of sinytra connector because that is the most drastic mod change I have made and the mod is in early beta and is still very buggy.
