CTD after exiting the Beta and reverting back to last stable

Do you have the same issue if you follow the OP’s steps to reproduce it?

Yes, I was getting strange CTD during SU10 beta, tried to opt out, now it CTD’s on launch.

Provide extra information to complete the original description of the issue:

Have also tried a full reinstall, as well as deleting community folders etc. Must be something lurking somewhere.
