Hi [NAME] welcome to this free user to user Alienware laptop discussion forum. This is not Dell Support.  Thank you for including the AWCC log in OP. It reports that an update was already in progress and thereby failed to install the Dell AWCC application.  Support for Dell G15 5511 Alienware Command Center Application, AWCC Version 5.5.0.0 Install instructions says Download file onto your system and then install (do not try to install over the internet). 
I just formatted my Dell G15 5511 to Win11 using Microsoft Installation Media from their site, and just can't install AWCC back. And since I can't install it, I can't use the RGB Keyboard, neither the G-Mode. OS Version: Windows 11 Home Single Language [22000.739] BIOS: Dell Inc. 1.14.0, 15/05/2022 CPU: i7 11th   Log: [IMAGE]
