Get a jade

I have a mk3 and the following happened to me:

I created my seed rolling dice, put into the coldcard with a passphrase.

When I exported it to sparrow, coldcard didn't consider the passphrase when generating the wallet and I didn't notice.

I deposited some sats to test, generating the receiving address with sparrow.

Then, when I tried to make a spending transaction with sparrow, the signature didn't work, and I don't remember if I got the same error as you.

I tried to do the same with seedsigner, and then the wallet gave a warning that that was a full spend transaction, meaning that the change utxo was going not to my wallet.

I realized that I had different wallets in coldcard (which was the same I imported in seedsigner) and sparrow and after investigating I discovered that the difference was that one of them was not using a passphrase.

Please check your wallet identifier in both coldcard and your hot wallet.

Hey! Wrong XFP means the extended fingerprint is incorrect. Meaning yours signing from the wrong wallet. Maybe you forgot to apply a passphrase you set before signing?
