What Operating System are you using? It appears from your 'specifications list' you don't mention that.
My next recommendation would be to re-install the operating system, and also, I would recommend IMHO, Windows 11 for your setup to function correctly. If you are using Alder Lake, Raptor Lake, Raptor Lake Refresh, or Meteor Lake and are not using Windows 11; I sincerely expect there to be numerous issues in abundance, IME.
Another thing you might want to check, is if there are any BIOS/Firmware updates for various components in your system.
You seem to not mention what type of drive you are using. This also is important, especially if you are using an SSD of some sort (I would not recommend the Operating System being on an HDD or spinning disk drive; by the way). There are firmware updates available all the time that are constantly being issued by the OEM/ODM. This also includes BIOS or Firmware updates for your motherboard.
Intel Arc is very temperamental, and these various recommendations could easily solve your issues automatically.
These are a few suggestions I can provide, before continuing on with troubleshooting the dGPU/Video Card itself.
