Wanted to play Subnautica recently, and relised Epic Games removed it from my library even though I am 100% sure I redeemed it

So I wanted to play some Subnautica multiplayer, and I have one copy on Steam and I remember redeeming it also on Epic, as the first ever game they gave out for free. And they removed it from my library! And I wasnt able to find where to directly ask Epic staff what happened.

Is there any way to get it back or text them to resolve that situation?
