so i have off hand combat in my modpack and it worked without issues but when i added armor hotswap it started crashing after i removed off hand combat it started working well again

if i have both off hand combat and armor hotswap the game won't load because it crashes
but i have one of them or none it works fine
i don't know if its a problem on the end of off hand combat or armor hotswap but i want to use both in my modpack
(my modpack is on forge 1.16.5 i tried starting the game with and without mixinboostrap, i am using the latest vesion of off hand combat)
