It is nothing like emergency, you have your hardware wallet like Trezor which you can even access with different wallet software like Electrum for bitcoin, Metamask for ERC20 etc, even if the official software of the wallet is outdated, you can use other software developers wallet to spend your coins. Not that your wallet is stolen, just that the company that produces it is no more existing, which makes this not to be an emergency.

Know that it is your coin, you control the keys, not the company that produces the hardware wallet, you have control over it. Because the company is affected, that does not mean your coin is affected.
