I have a similar problem while pluged into the MicroSD card and plugged into a USB card reader on my desktop. In my case, it turns out the MicroSD to SD card adapter that came with the card is faulty. I used another adpater on my laptop and formatted it, and it works flawlessly.
The faulty adapter works on my laptop’s card reader, though. I think the card is buggy if swapping adapters and using a non-USB card reader isn’t working. All in all, try different adapters and readers. As soon as you can open the drive and see “New Folder” at the top, you’re good to go. Hope it helps.
