Although the loss reporting of the credit card will be temporarily suspended, in this case, if you don't report the loss or activate a new card, the credit card can't be used, and you can neither swipe your card nor withdraw cash, which can reduce the credit card risk to a certain extent.
Loss reporting and cancellation of credit cards are two different things. As mentioned earlier, it is unsafe to report the loss when the credit card is not in use. After all, the account will be debited as long as it is debited normally, so it is safer to cancel the credit card that you really don't intend to use.
