problem just popped up here too. chkdsk is no help. sd card is still visible in file explorer, and did revive itself once, but a dead battery caused the problem to return. the first time, it became visible in storage again after viewing it in file explorer, and restarting brought back app access. hasn't worked again yet, so probably it was just dumb luck the first time.
here's something weird: I can still click on windows central notifications and access the app even though it's on the "unavailable" SD card.
