Garmin Instinct Esports - Heart rate problem

Problem with high, intermittent heart rate and watch freezing during GPS activity.

In a normal run, my heart rate is too high and I cannot work in the range of 130-150 heart rate because I would simply have to walk very slowly.

GPS activity may hang on the screen and only turning the device off and on helps

I have tried uninstalling Garmin Connect and installing and resetting the watch to factory settings and the problem still persists.
