Glitched gear after class change

I did a revert class change back to necromancer from crusader and I took my gear from my stash to put on and everything was fine till I tried to equip pyre’s allure off hand. The text of the item is cut off and won’t let me equip it… I tried to do a essence transfer thinking maybe it would fix the bugged out gear but my game crashes to a black screen and also it shows it is extractable but will not let me click it plz help
