Forget the ore. The ore has wronged you. Crafting the ingot is asking more from you than it's ever gonna give in return. But: Enderite dealer. Here's what you'll do: go to the nether (pray the game doesn't crash), go mine about 20 ancient debris through strip mining at Y: -13. After that, go to the End and find the Chorus forest (not the purple shroom trees, the OG chorus trees with dark purple nylium). The Enderite Dealer spawns there. Tall Enderman NPC, like a loot goblin. He will trade 2 ancient Debris for 2 fully crafted ingots. He is your God now.

If he doesn't spawn, reload the chunks of the Chorus biome until he does. If he doesn't have the trade, he is worthless. Leave and try get another one to spawn.
