First of all, you should ensure the SD card is well connected.
In detail, you can do these things
- Gently wipe the metal contacts of the SD card with a dry and clean cloth.
- Dusting the slot of SD card reader or adapter, or simply replace it.
- Use another USB port on your computer to connect the SD card adapter.
Secondly, you may have to go into the Windows Control Panel, Devices, and uninstall the SD Card Reader, and then reinstall it. I had that issue with a previous computer, and I believe it has something to do with doing a manual disconnect (safely eject?) before you physically remove the card.
If your SD card still not recognized or showing on your Windows PC, here are a number of ways to get your laptop reading sd cards: https://iboysoft.com/data-recovery/sd-card-not-showing-up.html
