Dear Milk,In this case, I recommend that you try to perform a clean installation of the NVIDIA drivers:
Download and run the latest driver package for your video card:https://www.nvidia.com/Download/driverResults.a...
Follow the onscreen instructions until you get the Installation Options window;
Select the Custom (Advanced) box and press Next;
On the next screen, you will be able to choose the components to install (all should be checked by default and if you're not sure, leave them that way);
In the Select driver component table, check the Perform a clean installation box and click Next;
Update Microsoft Store apps;
Open the store and click on Library;
Click on Get updates and wait for all apps to be updated;
Check if it is now possible to enable the option "Display GPU activity in the notification area";
Hope this helps, see you soon!
