It appears your Mesa and other graphics libraries are not from Ubuntu, but are from LP-PPA-system76-dev-stable and that might be confusing the standard VAAPI driver packages you have installed.
We can't support PPAs here so if you don't need Pop!OS then I would recommend removing the PPA from your system using 'ppa-purge'.
