[2021] Game crashes on start up

Depends on the crash message. You can post it here, it might be clear enough! But best bet is to reach out to fatshark.se/support - they're pretty quick to get back to you - just be sure to provide as much info as you can, such as the information seen when failing to launch, be it a windows error box dialogue or a crash GUID provided by our launcher.

Looked like your game was trying to boot up using integrated/onboard graphics. I'm going out on a limb to assume the game now sees your discrete graphics card and is working fine :)

Some CPUs/Processors have 'graphics capabilities' integrated in to them, fine for stuff that's not graphically intense like working on documents or browsing the web etc, not so good for 3D games (nor some 2D games for that matter).

The game looked to be trying to use the one in your intel CPU to run the game, which just wont meet the minimum spec. Since you solved it, it's likely the game now sees your dedicated graphics card.

I couldn't say. There's lots of reasons it could happen. Sometimes it's because the monitor is plugged in to the motherboard video output, rather than the GPU. Could be borky drivers or a misconfiguration somewhere in the AMD/Nvidia control panels.
