SD card Samsung S7 and now all my photos are gone and it says in my files the SD card on installed

I clicked something on my SD card on my Samsung S7 and now all my photos are gone and it says in my files the SD card not installed
how do I fix this

Try rebooting the phone. You probably unmounted the card, rebooting it will re mount it.

Thank You so much..Yes..Turned it off n Turned it back on and everything back to normal..Cheers
