My webcam is migrating inside of my screen; how can I stop this?

I purchased the device in May of 2020 and it has been in and out of warranty claims for the middle 7 months of the first year of ownership. Warranty won't accept it, even though it's been less than a year since the service was done. Regardless, what materials do I need to remove, save, then replace the screen and seeing how to stop my webcam from moving inside of the case. It stays at my desk and seldom moves. I avidly use the privacy shutter, but that seems to be a potential cause of the webcam issue. Webcam works fine as does everything else. I just need to do a fair amount of disassembly to reach the affected area and need some help. Thanks
