I set up just a /say hi command in my pretty big modpack, but it crashes when using it. Everything else works fine. If this is not a problem with your mod, Im sorry I asked.

It is a problem with Mine Menu. But you´re using an old 1.19 version. Please update to the 1.19.4 version, as the problem is not present there.
