For various reasons, the animation system can't properly update the node tree so that the socket availability caused by changing node enum properties propagates completely. So animating node properties that affect socket visibility to change isn't possible without issues like crashes. Unfortunately that wasn't disallowed before. In this commit there is a balance of disabling animation on sockets that could reasonably expected to affect socket visibility, and minimizing breaking changes.
