Found an instance of a user reporting the exact same issue on his S7, which he fixed by doing the following:
1) Navigate to Settings -> Lock screen and security -> Screen lock type -> Enter your current pattern -> None -> Keep fingerprints -> You will then be asked to set up a password.
2) Physically remove the SD card from the phone -> Reboot the phone.
3) When the phone has rebooted and is ON put your SD card back in. You will have window prompts for your SIM card pin and mobile data usage, and after that you should be on the encrypt SD card page. Click Encrypt. As your card is already encrypted it will be fast.
After that the SD card should be usable again.
