The only time GSX will bring itself 'back to life' is after a new AP is installed, and then only for the first P3D session. If, during the first session, you force the sim to reload by either changing location or selecting a different AC, then GSX and coutl will fail to load.
Ok, now your description is different again, and I'm starting to understand. It seems you have two problems at the same time: not starting on the 2nd session, and a problem with restarting in-game.
Umberto, I appreciate you are dealing with numerous posts with people having the same 'disappearing GSX' issue or similar issues, but the fact remains - with the previous version we were all happy simmers enjoying your great program
We are discussing a problem you are reporting, and I cannot see ANY difference in the number of "disappearing GSX" reports with this version. Like any other executable that runs with the sim, there are countless or reasons why it might "disappear", they are *always* caused by external causes, either conflicts with other addons and by other non flight-sim related software like antivirus/firewall or by issues with Windows.
There are so many different ways the program might not start but, the end RESULT would always LOOK simular, and it will be "GSX disappearing".
It's just that now, for some reason, it's happening to you, so you are assuming there must be a problem with the new version, or an increase in the likelihood of its disappearance with this version, which is not the case.
And please, with respect, don't tell us how it runs without issue on your Development machine. Try installing 75% of the ORBX Catalogue, the new FTX Central, 50% of Aerosims work, all of UK2000's airports, all of Fly Tampa's, plus other smaller fish - 29Palms, justflight etc... PLUS three or four Study level aircraft
I won't install anything from OrbX, because they never cared to reply to any of my request of cooperation about fixing all the issue their products cause to our sceneries (and so many others). But I have all the Flightbeam airports installed and several PMDG planes so no, it's just wrong assuming we test with just vanilla sim.
Sim, but then get your guys to break it anyway they can. That's their sole function. Whilst I also appreciate that not everybody may exhibit this issue, there has to be commonality somewhere.
It is your, and your Teams responsibility to ensure your product will function alongside others
It obviously does but, I hope you don't expect we could *fix* others problems.
If some developer, for example, insist linking against OUTDATED version of Simconnect, or doesn't respect (like we do, of course), the LM recommendation that a P3D add-on SHOULD be compiled using the VC++ 2015 redistributable runtimes (like we do), otherwise conflicts might happen, while we keep seeing other addon modules installing all different versions, what are you expecting we do ?
Perhaps you could supply a link to v2.1 with a non-functioning auto update, that will at least give us our scenery and a working GSX back. i haven't made a flight in four days!
Since the problem is surely not GSX, having a previous version won't help at all.
There's a KNOWN issue that we are trying to track it down, which is related to the new Windows Insider Preview version. At this time, there's no way to run GSX with it. We are setting up a test system with a Preview version, and we'll hopefully understand why, but it might take a while.
If you are not running the Windows Insider Preview, I'm afraid this is way to difficult to troubleshoot on the forum so, it's best we'd have a Teamviewer session, so I can check your system directly. PM me to arrange this.
