While having an item in the anvil and I try to shift-click lets say an enchantment book or anything else, it crashes my client, but the server still remains active.

@DireDiamond I need a crash report

I have the same problem, even when i move an enchanting book into the anvil with one of these weapons it crashes, i can send the report if needed too.

Yeah, if you can send a report. I think I know what the issue is, but I need to have a report to know for sure

Tried adding a precision book into a heavy crossbow and the game crashed.

Let your configs regenerate and will fix the issue. Delete your enchant_giver and mcdw configs on the server and the client
