CrazyTalk 8 known issues

Known issue#1: In Catalina OS (or the above version), during the 2D Actor face-fitting process, the face-fitting window would just disappear.

Known issue#2: CrazyTalk installer cannot work on macOS 12 Monterey or above version.

Since CrazyTalk 8 is a legacy product and obsolete, hence it will no longer be in development, then we would not be able to update some technical questions, especially with program crashes.

Note that CrazyTalk has no upgrade path.
