This is happening in Minecraft 1.20.1 with Majrusz's Accessories 1.2.3 and Majrusz Library 5.1.1
Im almost certain that this is an incompatibility with Kintsugi, a mod that modifies the librarian's trades and also does other things with enchantments (I tested with only Majrusz's Accessories, Library and Kintsugi, and it crashed, without Kintsugi it worked fine)
