Sorry to read that but I agree AWCC is very peculiar and loses functions often. I did a reset of Windows 11 and everything is back to normal (minus another unrelated hardware issue). So this is solved but unfortunately you need to do a reset so be prepared for a few hours of installing if these issues happen to you.  And if someone at Dell / Alienware sees this you need to make AWCC more stable it's problematic to lose thermal controls of the laptop really can affect the lifespan of the components. 
I have been trying for the last few hours to get  AWCC (Alienware Command Center) working on my m17 R4. It seems a BIOS update may have broken AWCC functionality as I was always prompted in AWCC to download an update which never worked (it would fail at about 70% and the button would light up again in AWCC to perform the update). I have tried multiple methods including Revo, clean boot install, following the Alienware YouTube video several times on uninstalling and installing AWCC. The only thing that worked after I uninstalled AWCC was installing it in the MS Store but again it would never update as before and had limited functionality. When attempting the install directly from Dell/Alienware the installer fails at AWCC_Core with the pop-up saying the "installation wizard was interrupted" error.  I have the error logs from both a Dell/Alienware failed install and a Revo traced install. Currently I don't have any AWCC installed so I can't control my FX or fans (main thing I use it for). Any help that is different from what I have tried above would be most appreciated at this point.
