Hi. I'm David, and I'm happy to help you.
The minidump indicates the driver "amdkmdag.sys" as the cause of the crash. This driver belongs to your AMD graphics card.
I suggest performing a clean install of the AMD graphics driver as instructed below.
Download the latest driver for your graphics card from the AMD website. Then, use the free DDU tool to remove the current driver. Then, install the latest driver using the installer you downloaded.
I suggest disconnecting from the internet during the entire procedure.
(Turn off Wi-Fi or disconnect the Ethernet cable.)
DDU: https://www.guru3d.com/files-details/display-driver-uninstaller-download.html
AMD driver download: https://www.amd.com/en/support/download/drivers.html
(Run the downloaded file and follow the on-screen instructions to install the driver.)
See if the system will work stably after this.
If the crash occurs again after doing this, share the minidump it created.
If you need a tutorial for using DDU, I recommend the video below.
