Issues with firmware for windows 11

Since upgrading to Windows 11, my laptop no longer senses my laptop's webcam (doesn't even appear under hardware devices when I open up the device manager) though my laptop's webcam was working perfectly before that. 

Though I have updated all the drivers, the Nvidia GPU is somehow disconnecting by itself and I find myself having to restart my computer multiple times while using apps like Blender and Solidworks. 

Lastly, both shift keys on my laptop have also stopped functioning. 

Let me know if anyone else is facing similar issues. Really disappointed in this laptop which I was previously quite impressed with.
