Looks like a crash in the Intel display driver. (It is attempting to call a null pointer function)

What graphics do you have?

First thing - try activating Vulkan.

This can be done on the startup screen. If you do not see it, pass the command line parameter +vid_preferbackend 1.

If this successfully loads the game, open the console, and type vk_listdevices

Note the number aside your NVidia device
and then type:
vk_device <#>

Then restart GZDoom.
