What ends up happening is that instead of being properly open upon insertion of the card, the metal shutter actually makes contact with the card connector and causing all sorts of possible issues, including invalid card data. As a last resort, try using some tape to tape the shutter in such a way that it is completely open. Then see if you still get invalid card data.

...this card has been in the same calculator for years. Then one day I turn on the calc and I get the Invalid card data warning.

Do you have another 48SX you can try it in? Although another card works OK in your original machine, it does not guarantee the card is bad. Try all combinations.
