Hello @Git-Forked, this issue should be reported to the game's developer(s). It looks like they've shipped their linux native variant of their game with missing dependencies.
Looks like we're in "compilers broke compatibility" territory, so taking a different approach to this... I dug up FNA 16.08 which is what Shipwreck ships with, and dug up the exact MojoShader revision that was used back ...
Looks like it depends on old internal files that have since been removed, here's another FixWreck [FixWreck.zip](https://github.com/ValveSoftware/steam-for-linux/files/15171933/FixWreck.zip)
It looks like lib and lib64 are empty, this usually happens because the folders were added in SVN/Git and revision control sometimes likes to ignore .so files specifically (not dll or dylib though ಠ_ಠ), so the PC that up...
