It’s possible that the connection between the chip and the antenna has broken, you may be able to temporarily get reads on it by gently pressing on the chip to try to get it to make a connection again Whoopsies, don’t do that
Also, it may be possible for Amal to swap the chip onto a new antenna, effectively reviving it (assuming the chip is still functional):
If you need/want any help with that, I’d be happy to help you figure it out again
