Help with Dash cam error “ please insert SD Card “

[Lopezash]

Hello,
I purchased a ddpai mola n3 pro dash cam and am encountering the same problem. Although I realize this thread is quite old, I'm posting here in hopes of receiving assistance.I've tested various SD card brands, including Kingston, with a 128 GB capacity (which is supported). I attempted formatting the SD card in FAT32 and also used the tool mentioned in this thread for formatting, yet the issue persists. Since acquiring it in July 2023, I haven't been able to use this dash cam. Because the SD card isn't being detected, upgrading the firmware isn't an option either. Could you please provide a solution?

card slot defect, try some product for oxidized contacts (apply to the card contacts - repeatedly insert - eject the card). Contacts card "cleaned" mechanically gently -- - just a piece of paper on a wooden stick

If it doesn't help - it's a HW defect
