ATTEMPTED MITIGATION
I've relinked libva-x11.so.2 to my libraries, reinstalled libva-x11-2 and tried again, and did a simple uninstall/reinstall of Steam. No help.

I'm hitting this very issue this morning, I did an update to my Ubuntu 22.04 as well. I also found suggestions to link to my local copies of libva-x11-2, but it did not help, so I reverted my changes.

I re-installed steam as well, no change.

I got it to launch, for those still struggling:
cd ~/.steam/ubuntu12_32/steam-runtime/usr/lib/i386-linux-gnu
sudo apt install libva-x11-2:i386
mv libva-x11.so.1 libva-x11.so.1-old
mv libva-x11.so.2 libva-x11.so.2-old
ln -fs /usr/lib/i386-linux-gnu/libva-x11.so.2.1500.0 libva-x11.so
ln -fs /usr/lib/i386-linux-gnu/libva-x11.so.2.1500.0 libva-x11.so.1
ln -fs /usr/lib/i386-linux-gnu/libva-x11.so.2.1500.0 libva-x11.so.2

The problem was the libva-x11 I linked to previously was the 64 bit version, so we have to install the 32 bit version first, then link to that.

This really should be patched in steam, but this works for me so far as a workaround (got past the update and the steam client loaded.)

This worked for me. I have been using the oibaf AMD drivers so I had to do a further driver dance, but this worked. Thank you for posting it.

After updating my Ubuntu 22.04 got this error.

Executing sudo apt install libva-x11-2:i386 worked. The libva-x11-2 (x86_64) was already installed.
