Windows 10: SD cards not initially showing/being read when starting up system

After reformatting my Legion Go, due to an unrelated issue, I seem to be having some issues with my SD cards being read. I have had my 1 TB reformatted also I initially noticed this through Steam where it did not show up in the storage section. After adding the card to the drive in steam settings, it would initially be shown, but when turning the Go on again, the card was not shown in the storage section. I tried my other SD cards to see if it was the card that went bad, but none of them would be "read". The cards are also not initially read in other store or the Legion Space game launcher.A

SD Card Slot Not Recognized

Thanks for that suggestion. Diskpart only sees one disk, the SSD. When I first received the SD card on Monday, it was working, but I did have some initial issues getting the system to recognize the card. I used the SD card to store an image of the system's SSD. - - - Updated - - -

Apparently, you are correct. I gave the slot a couple of shots of electronics compressed gas duster, and the system started to recognize the SD card. So, I cleaned the slot with 99% pure, anhydrous isopropyl alcohol followed by compressed gas and my Meco Eleverde Compressed Air Duster. The blow job seems to have resolved the issue.
