Can't boot up, can't change screen res

[ald232]

My boyfriend tried playing recently and his computer gives an error message when he tries to open the exe file. From my research, it seems it's connected to the screen resolution. His laptop (2022, custom with add ons) won't let me change the display res in settings--the option is grayed out. I have done screensharing with Dell etc. and spent >7 hours updating graphics card drivers and reading old forum posts and trying things recommended there (like adding "patchme" to file properties, opening w admin permissions, trying to open w special display settings, etc), but kept getting errors. Has anyone dealt with this recently? He previously was able to change his computer res and says he had to do that to play the game previously.
