PlayFab broken on linux since 2024-11-06

[lecterror]

Yesterday I was playing normally with my friend who is on Windows, today I'm getting the popup upon starting the game telling me that PlayFab cannot be loaded. But as mentioned, yesterday it was working fine, and I still have all the necessary requirements in my OS (I use Arch btw).

This seems similar to this issue.

Happened to me today too.

Looking at the "known issues" page on the Valheim support page, it looks like they have an in-progress ticket called "Steam Beta latest update breaks PlayFab on Linux native build"

It looks like this was found in "0.218.21 (n-31)", and my log says I'm running "l-0.219.14 (network version 32)", so I don't know if this is the same issue, or a new one, because if this wasn't resolved in the previous version, how did it work for us up until now??

Then there's the question of whether anyone from the dev team is even following this forum..?

Same issue here. I submitted a bug report yesterday.

Same issue here.

Found this in the patch notes for the recent Steam Client update: maybe it is related?

Native titles will execute in 'Steam for Linux runtime 1.0 (scout)' by default, instead of the legacy runtime environment. This behavior is consistent with Steam Deck and promotes better compatibility across all Linux desktop distributions.

Note that this new feature can be turned off globally with "-compat-force-slr off" on the Steam client command line.

Edit: launching the Steam client with that flag made the pop-up go away, but I don't play multi-player so that is as far as I can test it.

Steam pushed their client update from BETA to LIVE, breaking PlayFab. Devs are aware of the issue. PlayFab team has to update their libraries so that they are not dependent on Steam.

Looks like this *is* related, I ran the Steam runtime with these arguments, and we played Valheim today for hours with no issues. Thanks for digging this up!

Hopefully the devs fix this quickly, running Steam like this might cause problems with other games in the long run.

Another work around I've seen mentioned elsewhere would be to select "Force Proton Version" in the game's steam settings: basically this tells it to run the Windows build via Proton rather than the native Linux build.

Similar issues. Wife can no longer connect from XBox to my Valheim dedicated server hosted on Linux, server just has a big red X on it.

I also had to disable -crossplay in the server launch script so I could connect to the dedicated server from my Linux client.

Steam confirmed they will be adding pulse libraries to their Soldier runtime, which will make PlayFab work. The fix will only be available on Steam beta for some time.

Do we know when that will be released? The annoying thing is I have all the libs installed on the host system, so if only there was a way to run it 'unconfined' so to speak....

Which is the latest working version
What are the instruction to rollback client on windows and rollback the server using steamcmd ? thank you !
