minecraft 1.21
Mythicmetals-0.20+1.21-alpha4
i was trying to apply looting 3 to a diamond sword and when i put either the book or sword into their slot the game freezes then crashes shortly after below is a crash log.
anvil-crash-report-mythic-metals-alpha-4.txt

The crash seems to stem from bclib, which is used by BetterNether and BetterEnd

so if i remove both mods should it work fine? i havent entered/generated either the end or nether

You would likely also need to remove their dependencies. Looking at the issue tracker this is caused by bclib: quiqueck/BCLib#181

Looking more into the issue I cannot say if this is caused by Mythic Metals in any way. I will close this issue for now as I do believe this is on bclib's end
