Sometimes cleaning the SD card slot with some isopropyl alcohol and a toothbrush can help to resolve this issue
Also the Hero 5 was known for the water resistance being a bit of a hit or a miss so if it has been exposed to water I would recommend using this guide to check the device for water damage
Here’s a disassembly guide

Once again isopropyl alcohol is good at cleaning corrosion but water damage can sometimes need professional work

I would also check the formatting of the SD Card,make sure the GoPro can read it:-)
