Thank you.
Can you try to keep the laptop lid open, make sure the laptop display is main display (shows the notification and icons of the system tray)?
Please do that before starting any application using the better GPU. The issue is when the application starts, it can't list displays properly.
If you get it working like that, then I'm confident it's the same thing.
Lid open is also advisable to prevent computer getting hot and then losing performance because everything gets throttled.
Kind regards,
Alban
