Ok. I'm pretty sure this is standard and on by default on coldcards. When you enter your pin, you enter it in two parts - a prefix and a suffix. After you type the first half, you enter and it displays two random words to you which will be the same every time as long as you've got your pin right. This is to prevent you accidentally entering the whole thing into a phishing device.

If you have your coldcard paper back up, the correct two words likely are written on it. If you're entering your whole pin in the prefix without seeing any words, that may be the issue.

Although I'm not 100% sure - if you know that's never how you've done it before, maybe it wasn't a part of your setup.
