Set Jellyfin GPUs from 0 to 10 and the app status keeps to be "deploying"

Scale version: TrueNAS-SCALE-24.04.1.1

I’m using an Intel 12th Gen Intel(R) Core™ i5-12400 and an Arc A380 graphics card.

I suspect that the issue might be due to the app image not being configured according to the guidelines mentioned here: Intel GPU | Jellyfin

This is just my guess. Can anyone help me?

Usually you cant allocate more then 5 gpus in total and 1 per App, try to Set it to 1 and restart the app

Thank you.
But how can I ensure that when the number of GPUs is set to 1, it uses the Arc A380 instead of the iGPU?

Tried 1 and more GPUs, but it only deployed successfully with 0 GPUs.
