  • Because of an update to the game of Skyrim, the old SKSE will not work. To get out of it, you can update SKSE as well, or you can roll back the game to its previous version.
  • Sometimes, the Mods that you have installed create the problem, which is why SKSE64 won’t launch. So when you update the game, you have to update the Mods as well to work them properly.

So, above are the few possible reasons that cause this error. Now, get ready to see the solutions to this problem.
