[Solved] intel n150 quicksync woes

Debian Bookworm, Beelink s13 N150 mini PC

I am having trouble getting hardware transcoding enabled on Debian for Plex. So far I have:
-added /dev/dri path to my plex container
-enabled iGPU in BIOS
-installed the intel drivers
-enabled / disabled HDR tone mapping, as well as set "Intel Alder Lake-N" as -the hardware transcoding device in plex
-and I have updated the kernel to the latest backports release(6.12.9+bpo-amd64).

When i run the intel_gpu_top command I get this output:

intel_gpu_top: ../tools/intel_gpu_top.c init_engine_classes: Assertion `max >= 0' failed.

vainfo output:

vainfo output:
