3.7.1 SD Card not reading after print

I'm having issues reading from my SD Card after a print on my MK3S. Example; after a completed print, add new gcode on the same SD Card the printer doesn't recognize anything on the SD Card. It just shows the "back" icon and ".." 

The only work around is to power cycle the printer and it reads the SD card just fine. This happens only after a completed print and its super annoying. I never had this issue prior to upgrading to 3.7.1.

Try a new SD card; they don't last forever. Although that does seem like odd behavior for a failing card.

I have the same problem. Try fully inserting the card, then backing it out about 1mm. I have to fuss with it every time I remove the card. Contact support via online chat in the e-store.

Thanks for the responses. I thought at first it was an issue with the SD Card however I am able to read/write just fine on my mac/slic3r. It's certainly not an issue with the SD Card going bad, i've tried many different ones new/old and reformatted.  Nor is it limited to the same card with new gcode, I can insert a new card (with or without new gcode) with the same results - printer detects the card though its unable to recognize anything on the card. The only fix is to power cycle the printer.

Unless its coincidence and the card reader or LCD has gone bad, this never happened until after upgrading to 3.7.1 and i've been using prusa (mk2, mk2s, mk3, mk3s) printers for a long time. Anyways i'll contact support.
