Hi, I'm Bernard, a fellow Windows user. I'm happy to help!
Upon analyzing and checking the DMP files, the error you have is amdkmdag.sys. This is your AMD Graphics driver. In this case, we actually need to reinstall the AMD Graphics driver. Kindly follow the steps below:
Step 1. Completely uninstall the AMD GPU Driver using the steps from this link:

Watch out for ads on the site that may advertise products frequently classified as a PUP (Potentially Unwanted Products). Thoroughly research any product advertised on the site before you decide to download and install it.
Additional note: If the issue persists, I suggest removing the GPU and placing it into another PCIe port available (This is only applicable if you are using a Desktop PC or an External GPU). However, if all fails, I suggest contacting a local technician to physically check the device for any hardware-related issues.
