XPS 15 9570 GPU crashing

Hi there,

This can't be just me, but I'm having issues with GPU crashes in Windows.

I did a clean Windows 11 install, downloaded the latest BIOS and drivers about a month ago from the Dell support site (and since then, updated the Nvidia driver to 522.25)

The issue has occurred both in Adobe Lightroom and Unity. 

I will load the application, which uses the GeForce 1050TI GPU. Using it is totally fine, but then if I leave the laptop for a period, or if I switch to do something else, then return to the app, it crashes out and I get an error related to the display driver. If I restart the app, it is slow, like the Nvidia GPU isn't engaging, and only a system restart will sort it.

I'm almost sure that the GPU switching is to blame, but have no idea how to sort it? I've seen some solutions (older ones) saying driver updates work (but I'm on the latest versions of the drivers and apps), and others saying to disable one of the GPUs, but this isn't ideal?

Any ideas?
