I think the camera memory card is poisoned. I suggest you back up the necessary contents and format the memory card.

Three methods:

1, format the memory card with the camera's formatting function;

2. Connect the camera to the computer through the data cable. After the computer recognizes it, it will find your memory card, and a new drive letter will appear in "My Computer". Select the drive letter, right-click, and then click Format on the shortcut menu.

3. If there is a card reader, take out the camera memory card, insert the card reader, and then insert the card reader into the USB port of the computer. A new drive letter will also appear in My Computer. Select the drive letter, and then follow the above instructions.
