This is the second time now that GSX has randomly had a problem in MSFS2020. I loaded into a flight and noticed that I got the notification that GSX wasn't started, after restarting the couatl engine it crashed in the system tray. I've reinstalled GSX for the 3rd time now and it still has the same issue.
I seeked for help in the unofficial GSX Discord to which they responded that it was an activation issue. The product is fully activated via the FSDT Installer.
Any help would be appreciated, thanks.
