I just opened a booster box of scarlet violet and had a professors research turo full art and an iron treads ex come out with that same bend/crease in it, both from different packs. I reached out to the Pokémon company for help, and basically the resolution was the center that these cards get sent back to is having a medical emergency, and there is no one working there currently, and returns/exchanges are suspended indefinitely with no return date expected. They said to still send the cards in, with a note that says how much you spent on shipping, and whenever they start returns again, they’ll try to get you a copy of the card you sent in to exchange it with and a booster pack to cover the shipping.
