MIDI broken on linux

[waylon531]

Description

Recently ss14 midi instruments have broke on linux. I'm running the steam release and now I get an error when opening the instrument UI, and this error in the console:

/games/SteamLibrary/steamapps/common/Space Station 14 Playtest/bin/loader/fluidsynth.so: cannot open shared object file: No such file or directory

Is it a packaging problem with the steam release? Could it be a weird local version conflict and I have the wrong version of fluidsynth or something?
Reproduction
Open instrument UI or be near an instrument and the message appears.

Additional context
I'm running arch linux if that helps at all

install fluidsynth2 (or symlinking fluidsynth3 works fine it turns out)

I do have fluidsynth installed, and instruments were working fine until very recently. I just checked on master, and building everything myself makes instruments work fine, it seems like a problem with the steam release somehow
