2 days ago this was flawless, today, I can launch subnautica but not from vortex, nor do any mods load and i dont recall installing to my c drive but low and behold their it is. all my bethesda games are on the E drive (only subnautica is on my D drive as it uses sym-link deployment) so am fairly certain i would have opted to install it on the E drive for the hard-link deployment. i rolled back todays win10 update, kaspersky has no issue with vortex, unreal engine, or subnautica. As part of the process of elimination, I am going to re-install vortex now, if it wont let install to my E drive, I will try using steam mover. not sure what to do if that yields nothing... it leaves one thing, the Fences app from Stardock that i got to unclutter my desktop...might have overwritten something but then i can launch everything from the desktop just fine... ...maybe Subnautica and or the unreal launcher was updated and now blocks anything cheat like?
