If with "same issue", you mean the error discussed in the linked thread, it has already been fixed, by getting the FSDT Live Update. That error resulted in an error only when selecting an airplane without a GSX configuration, like the default F-35, and shouldn't happen anymore.
If, instead, you simply don't see GSX at start, the usual suggestions:
- Be sure you configure the antivirus to exclude the whole Addon Manager folder.
- Run the FSDT Live Update again
- Check with the Task Manager if a copy if Couat64_p3D.exe is not running from the previous session. If yes, Terminate it and start the sim.
