Can confirm. i have the same issue.

I'm having the same problem. After some searching it kinda looks like the Electrum Knife is missing and the forge tag that adds the Electrum Knife to forge:tools/knives points to the missing item. I removed the tag from the .jar file and everything seems to work again.

Edit: Removing it didn't work. I ended up re-adding all my knives to the tag using CraftTweaker.
Edit 2: It seems the tag farmersdelight:straw_harvesters is also broken because of this.

Can confirm heres my log about it https://mclo.gs/yXNAN6Y

This is on 1.19 right?
