Need help, changed reslolution now cant open game without a black screen.

So i was in game and changed resolution(by accident choose a the smallest one) i got instant black screen. So i closed game and opened just to get instant black-screen.
I have tried running as admin, change resolution and some other stuff in config.wtf without success.

As i have used a lot of time to fix my add ons, and tempered to perfection for me i dont wanna delete->reinstall.
Anyone have a solution for me?

Thanks in advance! :) have a great day!

Try simply deleting WTF folder

Thanks alot for the help :)
