in theory it may be fixable, but HDMI cables connections are delicate so you would probably have to send it back to the manufacturer where it may fall under its warranty guidelines, but with that said they may not be able to fix it.
This is part of the reason why you don’t see field terminatable HDMI cables out there.
It may also be less expensive to just buy a new one.
I don’t know who manufactured the cable, but I know companies like Transparent, Straight Wire, Tributaries are companies that back their products and have policies to protect their clients’ purchases. It’s part of the value of spending a little bit extra to buy products from manufacturers of this level.
Some people view cabling as throw away items, but they are an under valued part of the system equation.
