Hey there Ab!
My name is Miguel Ángel and I'm an independent advisor, also a Microsoft user just like you! I'll try to help you today with your issue.
The only Razer Book that is compatible with Windows 11 is the model RZ09-0357, which I think is the one you're using, if you can confirm.
Could you please run your system in Safe Mode and Clean Boot and check if the issue persists in both modes? Instructions are here:
CLEAN BOOT: https://support.microsoft.com/en-us/topic/how-t...
SAFE MODE: https://support.microsoft.com/en-us/windows/sta...
You may also want to disable any third-party antivirus and just use Windows Defender. Same with any software that may interfere directly with your device and its settings like optimizers and all that.
Follow the instructions given by Razer for these specific issues and tell me how it goes as well: https://mysupport.razer.com/app/answers/detail/...
I'll wait for your reply! Don't worry, everything will be okay :)
