I can add an update to this question but I'm still seeking a more official answer. A generous, private developer has made some modifications to the 2014 source package for Core Image Funhouse to allow it to partially function under MacOS 10.15 (Catalina). I've used it for a few hours and it seems mostly functional although it crashes once in a while. Here's the link to that... https://github.com/dhoerl/CoreImageFunHouse With that said, I have to think that this app was replaced by some other process within xCode or by some other developer app, plug-in or extension. If anyone has any further information or tips please share. I've noticed a lot of people asking similar questions spanning the last few years. Thanks

Having a similar issue. "Error Downloading Crashes List" An error occurred preventing xCode from downloading crashes list. "username" failed with error: Waiting for future 'CrashPointNetworkListSource' to complete timed out. I don't see any agreements that need to be dealt with or certificate or log-in issues. Just keeps failing.
