This has happened to me before but installing a new addon manager solved it. Not this time.After adjusting some gsx parking positions the couatl engine shut down. With an error. Installing a new addon manager did not fix it, I uninstalled all my fsdreamteam and flightbeam products and got new installers for all of them. I reinstalled and still no building anywhere. Please note I have no AV on my fsx machine at all and Windows Defender Service is off. This is one of the panic logs couatl created, not sure what is going on.
