I attempted to charge a new Hero8 Black using an Apple 10W (iPad) charger. The battery never fully charged and when another attempt to charge was made the red LED blinked only once then no further charging. Following an online chat the original battery was replaced. The 2nd battery started charging using the same 10W Apple charger but at 29% an overheat message appeared and charging stopped. Now the 2nd battery will no longer charge. Specs say 5V @ 2A (10W) is acceptable.

Have you tried charging it using other adapter?
Try to use your computer's USB port or use other adapter and check if that will make any difference.
If issue persist reinstall your camera's firmware: https://gopro.com/help/articles/block/How-to-Update-GoPro-Cameras
