possible fix to everyone else getting the crash before the bethesda logo, a new install of skse aint gonna help ya, your problem is in your skyrim directory. Find the folder called SKSE, in it you will likely find another folder called Plugins, delete the SKSE folder. I don't know what it was doing there, because reinstalling SKSE doesn't cause this folder to appear, i think i may have accidentally installed or tried to install SKSE through Vortex with the rest of my .Zip and .rar and .7z files that were in my manual mods installation folder. Either that, or it was put there by one of the mods I was intending to use. If I find out what exactly was doing this, I'll post an edit. Good luck and I hope this helps.
God THANK YOU SO MUCH........You solution is the problem fixed!
My whole Xmas hols were ruined because i could'nt access SkyrimSE via SKSE64.......it was exactly this folder you talk about..
Thanks again! :-)
