Bad SD card reported for two different cards

I’ve had a eufy cam system for several years. A few months ago the home base reported that the SD card was bad. This is strange because they don’t tend to go bad in my experience. But I ordered a new one, and the home base now complains this card is bad, too. Multiple repair / reformat / reboots don’t fix then problem. Feels like the home base has a problem. How can I get this fixed?
