I have a strange situation with AMS2 only. It will Alt Tab out of the game on it's own after a few minutes and will continue this pattern until I get out of the game. I can Alt Tab back into the game exactly where it left off. It will do this only while I am in AMS2. Does not matter if I am in VR or playing via the monitor. However, I can play AMS2 Beta with no problems! I have verified the AMS2 files and they are fine. I have uninstalled AMS2, deleted document folders and reinstalled. Any ideas of a solution besides simply play the Beta version? No mods installed. No other sim (ACC, AC, RRRE or Rfactor 2) has this issue. Thanks.
Just a follow-up. After disabling all windows notifications, enabling focus assist to priority while gaming, uninstalling and reinstalling adobe creative cloud, my alt-tab problem has seem to gone away. I think the adobe creative cloud was the culprit based on the event viewer. For some reason it could not log me in automatically so it kept trying and failing to do so. After reinstalling it, auto login is now working again. I play AMS2 far more than the other sims including the AMS2 beta version. I guess that contributed to AMS2 to being the sim where I saw the problem and not the others(?).
