The newest releases of SteamOS and Linux had an update to the glibc library that broke the edition of FMOD that Cyberpulse runs. This was causing the game to crash on startup on updated Steam Decks and Linux machines running the latest OS versions.
Thankfully there was a way to manually tweak the flags on the FMOD executable—Cyberpulse now boots smoothly on all hardware running SteamOS and Linux!
