The latest beta release in steam-native wouldn't run because it was missing lib32-libva:
`Error: You are missing the following 32-bit libraries, and Steam may not run:
libva.so.2
libva.so.2
libva-x11.so.2`
Installing it sorted that out. I had already installed libva (64bit) for another package, but removing that didn't prevent steam-native from starting, so I'd assume it might not be needed. I also checked whether the older version, lib32-libva1 is still needed, and it worked without that as well.
The non-beta version of steam doesn't require that package as of yet.

Additional info:
pacman versions:
steam 1.0.0.61-3
steam-native-runtime 1.0.0.61-1

Steam package version: (of beta)
1573176642
Steam package version: (of stable)
1573019481

Steps to reproduce:
Install steam and steam-native-runtime
Make sure lib32-libva isn't installed

In
Steam>Settings>Account>Beta participation
select Steam Beta Update

Then run steam-native, it should
