Try running the Nvidia Control Panel as administrator
The first thing you should do is try and run the Nvidia Control Panel as admin to see if Windows is restricting the program’s access.
Press the Windows key and search for Nvidia Control Panel. Once the tool shows up in the search results, either right-click it and run as administrator or click the option on the right. Once the panel launches, check to make sure you don’t have any permission issues.
Make sure all Nvidia services are running
The control panel requires a few services to be running in the background. First, check to see if any of them are inactive.
Step 1: Press Windows key + R to bring up the Run prompt. Type in services.msc and hit enter.
Step 2: Find the Nvidia Display Container LS service and double-click it to proceed.
Step 3: Ensure that the Startup type is set to Automatic and that the service is running. Click Apply followed by OK when you’re done.
Now restart your PC and try re-accessing the control panel.
Restart Nvidia processes
An issue in a process can also cause permission access issues. Restart all running Nvidia processes to see if that resolves your issue.
Step 1: Right-click on the taskbar and click on Task Manager.
Step 2: Close any Nvidia processes you see. Especially the ones named Nvidia Contain.
Now try starting the control panel again, and it should work just fine.
