Versa sensor light of heart rate stopped working.

[Foxina9]

Hello, guys.

Is there anyone who could help to solve my problem?
I was charging after workout as always my watch Versa,

and as I finished on fully charged, I put the watch back on my hand as usually.
After day I realized as I worked out, that something is wrong with my watch as of heart rate.
I could not have less than 150 calories after hour of heavy lifting. It didn't make sense, usually I lost 300-400 calories per day of my workouts, and now all the sudden this?
So I thought maybe my watch frozen, but it repeated the same process also next two days.
Then I realized and understood, there is something wrong with my watch as I put it off and saw no light and my heart was for the same 3 days only 86 bpm. I was like : what is going on?
I tried as many resetting and factory reset, hard reset to fix the sensor from YouTube videos, but none of them helped. If anyone knows or it happened the same problem as me, please let me know!
Truly thanks.
Greetings,
Foxy.
