Steam will launch the game instantly under a few instances- The skyrim_launcher.exe has been replaced by the game executable (or skse's executable). This would be a manual thing, like a drag/drop. Steam, Vortex, nor SKSE do this in an automated fashion. the game is started with an unusual Launch option (one that I'm not familiar with) to skip the game. the game is launched via a short-cut outside of steam.In the case of 1, you can fix this by verifying the game local files (don't forget to re-do the xedit clean of the plugins). In the case of 2, remove the launch option from the general tab of the game itself. In the case of 3, launch the game from within steam's window, under library. other than that, your guess is as good as mine?
