my AN517-54 laptop uses integrated graphics instead of nvidia

Does this happen only in the benchmark or every game?

Every game and app uses integrated graphics. I downloaded the benchmark just to show you. It does say Nvidia graphics card but according to the task manager, during the benchmarking process Intel integrated graphics were used like any other application. Nvidia only works for a while after reinstalling the driver and then everything switches back to Intel UHD

Do you still see the Nvidia GPU in the device manager?

Yes but the usage is 0% and the temperature is only 50-55 Celsius. After reinstalling the driver it works normally, I start the game, but after half an hour during the game it starts using only Intel UHD

Edit:Sorry, I thought you wrote task manager, yes in device manager I see Nvidia graphics too

yes, I still see NVIDIA in the device manager

Try this: turn off the laptop, unplug the charger, and hold the power button for 15 seconds. Also, try to update the BIOS if it does not help.

@AnhEZ28 I just tried installing an older Nvidia driver (November) and it worked, but it was strange that both graphics cards (integrated and Nvidia) worked at the same time when playing games, about 30% integrated and 30% Nvidia. Is this okay?

That is fine. The processed graphics from the Nvidia GPU has to go through the Intel GPU.
