LINUX ERROR: missing libfmodstudio.so.8
SOLUTION:
install "execstack" using your operating system's package manager.
cd into the directory where the game is saved
cd into either "lib64" or "lib" depending on if you're running 64 or 32 bit game version.
execstack -c libfmodstudio.so.8
If that doesn't fix it, then also do:
execstack -c libfmod.so.8
This happens due to glibc plugging a security hole. See https://qa.fmod.com/t/glibc-2-41-breaks-loading-fmodstudio-libraries-in-standalo...
Developer can fix it by recompiling using updated FMOD.
