not sure if it's the same issue i had but on my aurora r12 I installed Command Center and the Thermal and Overclock sections would just hang (like you said) just spinning but never loading.

Everyone said to just reinstall command center (among other things) and nothing ever worked until I figured out what to do:

 

First download: 1) Alienware Command Center as well as something called 2) Alienware OC Controls Application (this download got the thermal and overclock sections to work finally).

 

So to sum it up, you need to download 2 things to get the thermal and overclock sections to work.... at least that's what finally fixed mine and got the spinning icons to finally load. For reference I'm running Aurora r12 with Windows 11.
