19.18 no more HRV and sleep recording

Downloaded 19.18FW unintentionally while only wanting to update the maps. Many features are broken since, dont get any sleep and HRV recordings at night. Does anyone have a clue what to do? 

Garmin is driving me insaine with their one step forward 3 steps back software development. Try to get this fixed, sell the watch and see if the competiton is doing any better. The productline is way to expensive when so many features are so buggy and unstable.
