Hi, thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today, my timezone is UTC +8.
I understand the issue you have, there is nothing to worry I am here to help, since you have set the GPU to high performance, kindly change the preferred processor by following the steps below:
Open the Nvidia Control Panel > Select "Configure Surround, PhysX" > Under "PhysX settings" choose your Nvidia Processor.
Once done, restart the PC and check.
Note: If the issue persists, we need to run a Clean installation of the Nvidia driver, this is different from doing DDU or updating the driver as this will remove all entries and replace them with compatible ones, kindly follow the steps from the link below:

Note: This is a non-Microsoft website. The page appears to be providing accurate, safe information. 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, however, if all fails, I suggest contacting a local technician to physically check the device for any hardware-related issues.
Let me know how it goes and I hope that helps.
Bernard
