Same problem with FSX, but only if I try to install my FSDT airports, if using just GSX after new set up, it works.

Your version of the Couatl engine is outdated, the current version for P3D, is 5809 and it has been released a day before your post (June 7th). As usual, run an update Check, and if you still outdated (likely because your internet connection has trouble accessing cloudflare), just the OFFLINE Installer.
