The log doesn't say much, other than saying it started generating the airport cache, but crashed, the most likely cause is the antiviurus:
- Turn off the firewall
- Configure the antivirus to add the whole Add-on Manager folder to the antivirus Exclusions list.
- Download and install the new FSDT Universal Installer:
https://www.virtualisoftware.com/update/FSDT_Universal_Installer.exe- Install it and use it to Update GSX and other FSDT products you might have.
If still doesn't work, try to RESTART Windows after installing the Universal Installer
If that doesn't fix it, it might be a corrupted .BGL in your scenery library. A new log, made AFTER you did all the suggested changes and the update will help.
