I get the same error on Ubuntu 20.04.3. The problem here is likely
caused by Mesa drivers update to 21.2.6. Looks like Mesa 21 has changes
in Wayland authentication and it requires fix to libva
(https://github.com/intel/libva/pull/476). The fix should be present in
libva 2.11 and above while Ubuntu 20.04.3 ships libva 2.6.
I verified it using compiled libva/libva-utils from current upstream
git. with current upstream

Please update libva/vainfo in 20.04.3 to match Mesa. I can open new bug
for 20.04 if needed.
