It's not the actual cause, the issue is with the Steam library loading the wrong copy of itself. The code in the repository has this fixed but not the build yet, I'm working on cleaning it up and adding the missing tests for the new functions at the moment.

Afronanny does have a point though, if the interface versions don't match, some of the forwards/natives wont work/be reliable. Steam_RestartRequested is the most obvious one that comes to mind.
