Why does the Apple Watch Workout stop reading my Heart Rate?

I've been having this issue since Watch Series 3 and Watch Series 6 a few months later (on WatchOS 9 is when it did this FYI). When I finish charging and I start a workout to go for an Outdoor Walk, my heart rate stops working.

It begins from 115 BPM my normal heart rate on a brisk walk down to 90 BPM and starts circling to find my heart rate. It only works again if I have Heart Rate app on the watch and check my pulse once it stops working. It blacks out and no Zone Recording is completed for a length of my exercise of 30 minutes.

This has been an ongoing issue for me. It used to be a problem mostly during swim workouts. Then it was HIIT type workouts, which I read is often a problem with the sudden changes of highs and lows of the heart rate.

But today I took a somewhat brisk walk (the dog was slowing me down). Watch never moved on my wrist, I wasn’t sweating, nice steady pace and look how little the watch picked up my heart rate. Only 14 minutes out of 54!
