FSDT Installer prematurely exits after Fenix 2.2.0.232 update

[kconlon]

Recently updated Fenix A320, there was a popup asking to go into FSDT Installer, and reset the config for GSX.  When I do that the FSDT installer exits when it gets to the Updating layout.json for Fenix A320 B2. 
Tried to post a video but it must be too large. https://1drv.ms/v/s!Auszx9WFJTka-gXSu9cua70_e8p_?e=RYJcJw
The event viewer lists this:

I started with AntiVirus Off. I deactivated all selected aircrafts from FSDT Installer of GSX Pro page. Uninstalled Fenix A320 and deleted all Fenix traces left by the uninstaller. Rebooted machine and started with the new Fenix A320 Installer. I went back to FSDT GSX Pro and activated all aircrafts I had before. Launched to MSFS2020, loaded Fenix A320 and all went just fine with no issues related with GSX yet.
I hope this help to others.
