It’s not a problem with the add-on. It’s an issue with one of the MSFS cgl files. If you’re willing to wait a week, It should be fixed in SU7. If you don’t want to wait you can rename the file so that MSFS doesn’t load it. You lose a few buildings but that’s better than a CTD.
Details about which file to rename are in this thread: KADW - Andrews - CTD Analysis by Community contributions
