Your best bet is to go to /Documents/Paradox Interactive/Stellaris and move settings.txt out of the folder, and then reload the game. You'll likely have to reset your resolution and stuff, but it should load this way.

If that doesn't work, you can go to support.paradoxplaza.com and open a ticket.

Hope this helps!
