Bug Report: Heart Rate Subsystem crashes after firmware update

Hi,

Since firmware 20.26 update,  I am having these recurrent Heart Rate Subsystem crashes and recoveries.

Both Wrist HR, and External Band HR crashes at same time. (and Fit File Record message 135 as well as hr derived metrics) .

No Wrist HR, and External Band HR values in the activity fit file record messages

Other functionality doesn't seems to be affected

Before that HR was faultless
