The stupid #goproHero11 (as any other model since the beginning) simply cannot load a battery. Device cannot stay off after switching off. After a whole night of randomly switching on the battery is finally in deep discharge state.
You have to remove the battery and charge externally in a special extra charger.

Because fixing bugs seems impossible in that company also their timestamps keep being broken.
#wtf #gopro
Edit: did not see they are going bankrupt these days, I wonder why ;)
