If your camera is currently frozen, try to reset the camera by holding the MODE button for 10 seconds (hold the top SHUTTER button on the HERO Session / HERO4 Session).
Should the camera not prompt a reset, remove and then reinsert the battery to get it unstuck (for cameras with integrated batteries, Step 1 will imitate a battery pull).
Make sure you have the most current software on your camera.
