When possible, attach your MCreator workspace (or even better a minimal example workspace required to reproduce the bug), game crash logs (full logs, do not crop them, in text format, not screenshots of logs) from the Console tab or terminal and steps to reproduce the bug in your workspace. Please specify which mod elements to check in your workspace too, if applicable.

I need workspace, not mod file.

Did you specify repair items, without any repair items specified, your sword will crash the game indeed when trying to be repaired in the anvil.
