SerializationException error
[Note::; for some reason, this forum's post editor doesn't properly display the number nine or the colon for me. So in places where a nine was needed, I typed a "P".]
Hi Chris,
My project is using Unity 5.6.0f3 and AC 1.56g.
This has been my stable build setup for my current project for a while, but recently I updated Unity to 201P.1.10f1 and AC 1.68 to work on a new, separate project. Though I expected that this would have no effect on my previous project since I read that you can have concurrent versions of Unity on the same machine, it still ended up with a problem. Now, when I open that older project and try to play a scene or click on the "settings" tab in the Editor window, I receive the following error:::::::...

This is when you're still opening the old project in Unity 5.6?
Do the two projects share the same name or "save filename" fields? It sounds like it's (somehow) reading options data from the newer project.
You could try clearing the PlayerPrefs, which is where the Options data it's complaining about is stored. See the suggestions made in these links:

Hi Chris, you we're right on about this one (as usual)!
So, in case this happens to anyone else, the way I fixed it was to rename the "save filename" field to make sure the name was different for the 2 versions. Next, on the newer version of Unity, I used the "Edit > Clear all PlayerPrefs" feature. This did the trick for me.
