Anti cheat crashes when using laptop but not when using laptop + monitor

Exactly as the title says, when playing on the laptop by its self it will crash when booting (on steam, I dont play via the launcher) or it will load but the anti cheat has crashed/ not loaded so I cannot play online. This changes when I plug the laptop into a monitor and I have no idea why. I have tried
Redownloading warthunder, verifying files, changing resolutions, changing graphics, repairing windows ( due to it sometimes being a kernal error. I am running out of ideas and noone else seems to have this weirdly specific problem.
The laptop I am using is the Asus v16
