Just wanted to update that I have since upgraded to Watch Pro Version 11.0.0.49 and the issue is still occurring. App version is still the same on IOS - Sleep data is also not showing in the charts as well.
UPDATED 01/04/24:
Saw there was a update released yesterday to the IOS App and it is now version 2.2.16 with a reset of the watch and the main issue is still occurring. Heart rate chart now shows resting heart rate and nothing else. All other charts are still empty.
UPDATED 01/16/24:
New update to watch - V11.0.0.50. Reset watch and issue is still occurring. App version is still 2.2.16

New update to app - V2.2.20. Reset watch and issue is still occurring. Watch version is still V11.0.0.50

I sold the watch. Seeing that there is no support from the company or the mods here, I have purchased a apple watch. Hope this issue gets fixed for the rest of you
