Resting heart rate on health app has not updated in 5 months

Everybody, my Apple watch always used to track my resting heart rate. But the last updated tracking was in November of 2023. I'm pretty sure it's because I connected an external heart rate monitor as well to the health app. The heart rate monitors called COROS heart rate monitor. Anyways, I'm pretty sure that is what forced my Apple watch Ultra to stop tracking my resting heart rate and sending that data to my health app. Also my cardiac variability has not tracked since November as well. Those are the only two. I've tried to read through forums and I've tried out multiple different things and nothing has worked. Any recommendations would be a super helpful. Thank you so much for the help.
