Same problem game crashes on load.
found in log files:
Fallback handler could not load library /Users/muted/Library/Application Support/Steam/steamapps/common/Humankind/Humankind.app/Contents/Frameworks/MonoEmbedRuntime/osx/libPhotonEncryptorPlugin
Tried Update Preview, current version and rollback to earlier version, same problem.
Game doesn't start at launch. Loading wheel just keeps spinning. I was able to fix that before by validating installed files, but not anymore
